    Java8-291之后 , 禁用了TLS1.1 , 使JDBC无法用SSL连接SqlServer2008怎么办,以下是解决办法

    修改java.security文件

    1.找到jre的java.security文件

    如果是jre , 在 {JAVA_HOME} / jre / lib / security中, 比如????

    C:\Program Files\Java\jre1.8.0_301\lib\security

    如果是Eclipse绿色免安装便携版
    在安装文件夹搜索java.security ,比如????

    xxx\plugins\org.eclipse.justj.openjdk.hotspot.jre.full.win32.x86_64_16.0.1.v20210528-1205\jre\conf\security

    如果是window下的安装版Eclipse
    文件在c:/用户文件夹/.p2/pool/plugins/…中, 例如????

    C:\Users\admin\.p2\pool\plugins\org.eclipse.justj.openjdk.hotspot.jre.full.win32.x86_64_16.0.2.v20210721-1149\jre\conf\security

    如果在C盘搜索java.security,可能搜出两个以上,temp文件夹中也有

    2.打开java.security并搜索 “jdk.tls.disabledAlgorithms=”

    jdk.tls.disabledAlgorithms=

    可找到????

    # Example:
    #   jdk.tls.disabledAlgorithms=MD5, SSLv3, DSA, RSA keySize < 2048, \
    #       rsa_pkcs1_sha1, secp224r1
    jdk.tls.disabledAlgorithms=SSLv3, TLSv1, TLSv1.1, RC4, DES, MD5withRSA, \
        DH keySize < 1024, EC keySize < 224, 3DES_EDE_CBC, anon, NULL

    3.删掉TLSv1, TLSv1.1,

    删掉后变为????

    # Example:
    #   jdk.tls.disabledAlgorithms=MD5, SSLv3, DSA, RSA keySize < 2048, \
    #       rsa_pkcs1_sha1, secp224r1
    jdk.tls.disabledAlgorithms=SSLv3,   RC4, DES, MD5withRSA, \
        DH keySize < 1024, EC keySize < 224, 3DES_EDE_CBC, anon, NULL

    4.保存,可以了

    修改后的样例,jre8可直接复制

    已测试通过

    #
    # This is the "master security properties file".
    #
    # An alternate java.security properties file may be specified
    # from the command line via the system property
    #
    #    -Djava.security.properties=
    #
    # This properties file appends to the master security properties file.
    # If both properties files specify values for the same key, the value
    # from the command-line properties file is selected, as it is the last
    # one loaded.
    #
    # Also, if you specify
    #
    #    -Djava.security.properties== (2 equals),
    #
    # then that properties file completely overrides the master security
    # properties file.
    #
    # To disable the ability to specify an additional properties file from
    # the command line, set the key security.overridePropertiesFile
    # to false in the master security properties file. It is set to true
    # by default.

    # In this file, various security properties are set for use by
    # java.security classes. This is where users can statically register
    # Cryptography Package Providers ("providers" for short). The term
    # "provider" refers to a package or set of packages that supply a
    # concrete implementation of a subset of the cryptography aspects of
    # the Java Security API. A provider may, for example, implement one or
    # more digital signature algorithms or message digest algorithms.
    #
    # Each provider must implement a subclass of the Provider class.
    # To register a provider in this master security properties file,
    # specify the provider and priority in the format
    #
    #    security.provider.=
    #
    # This declares a provider, and specifies its preference
    # order n. The preference order is the order in which providers are
    # searched for requested algorithms (when no specific provider is
    # requested). The order is 1-based; 1 is the most preferred, followed
    # by 2, and so on.
    #
    # must specify the name of the Provider as passed to its super
    # class java.security.Provider constructor. This is for providers loaded
    # through the ServiceLoader mechanism.
    #
    # must specify the subclass of the Provider class whose
    # constructor sets the values of various properties that are required
    # for the Java Security API to look up the algorithms or other
    # facilities implemented by the provider. This is for providers loaded
    # through classpath.
    #
    # Note: Providers can be dynamically registered instead by calls to
    # either the addProvider or insertProviderAt method in the Security
    # class.

    #
    # List of providers and their preference orders (see above):

    #
    # A list of preferred providers for specific algorithms. These providers will
    # be searched for matching algorithms before the list of registered providers.
    # Entries containing errors (parsing, etc) will be ignored. Use the
    # -Djava.security.debug=jca property to debug these errors.
    #
    # The property is a comma-separated list of serviceType.algorithm:provider
    # entries. The serviceType (example: "MessageDigest") is optional, and if
    # not specified, the algorithm applies to all service types that support it.
    # The algorithm is the standard algorithm name or transformation.
    # Transformations can be specified in their full standard name
    # (ex: AES/CBC/PKCS5Padding), or as partial matches (ex: AES, AES/CBC).
    # The provider is the name of the provider. Any provider that does not
    # also appear in the registered list will be ignored.
    #
    # There is a special serviceType for this property only to group a set of
    # algorithms together. The type is "Group" and is followed by an algorithm
    # keyword. Groups are to simplify and lessen the entries on the property
    # line. Current groups are:
    #   Group.SHA2 = SHA-224, SHA-256, SHA-384, SHA-512, SHA-512/224, SHA-512/256
    #   Group.HmacSHA2 = HmacSHA224, HmacSHA256, HmacSHA384, HmacSHA512
    #   Group.SHA2RSA = SHA224withRSA, SHA256withRSA, SHA384withRSA, SHA512withRSA
    #   Group.SHA2DSA = SHA224withDSA, SHA256withDSA, SHA384withDSA, SHA512withDSA
    #   Group.SHA2ECDSA = SHA224withECDSA, SHA256withECDSA, SHA384withECDSA, \
    #                     SHA512withECDSA
    #   Group.SHA3 = SHA3-224, SHA3-256, SHA3-384, SHA3-512
    #   Group.HmacSHA3 = HmacSHA3-224, HmacSHA3-256, HmacSHA3-384, HmacSHA3-512
    #
    # Example:
    #   jdk.security.provider.preferred=AES/GCM/NoPadding:SunJCE, \
    #         MessageDigest.SHA-256:SUN, Group.HmacSHA2:SunJCE

    # Sun Provider SecureRandom seed source.
    #
    # Select the primary source of seed data for the "NativePRNG", "SHA1PRNG"
    # and "DRBG" SecureRandom implementations in the "Sun" provider.
    # (Other SecureRandom implementations might also use this property.)
    #
    # On Unix-like systems (for example, Linux/MacOS), the
    # "NativePRNG", "SHA1PRNG" and "DRBG" implementations obtains seed data from
    # special device files such as file:/dev/random.
    #
    # On Windows systems, specifying the URLs "file:/dev/random" or
    # "file:/dev/urandom" will enable the native Microsoft CryptoAPI seeding
    # mechanism for SHA1PRNG and DRBG.
    #
    # By default, an attempt is made to use the entropy gathering device
    # specified by the "securerandom.source" Security property.  If an
    # exception occurs while accessing the specified URL:
    #
    #     NativePRNG:
    #         a default value of /dev/random will be used.  If neither
    #         are available, the implementation will be disabled.
    #         "file" is the only currently supported protocol type.
    #
    #     SHA1PRNG and DRBG:
    #         the traditional system/thread activity algorithm will be used.
    #
    # The entropy gathering device can also be specified with the System
    # property "java.security.egd". For example:
    #
    #   % java -Djava.security.egd=file:/dev/random MainClass
    #
    # Specifying this System property will override the
    # "securerandom.source" Security property.
    #
    # In addition, if "file:/dev/random" or "file:/dev/urandom" is
    # specified, the "NativePRNG" implementation will be more preferred than
    # DRBG and SHA1PRNG in the Sun provider.
    #

    #
    securerandom.strongAlgorithms=Windows-PRNG:SunMSCAPI,DRBG:SUN

    #
    # Sun provider DRBG configuration and default instantiation request.
    #
    # NIST SP 800-90Ar1 lists several DRBG mechanisms. Each can be configured
    # with a DRBG algorithm name, and can be instantiated with a security strength,
    # prediction resistance support, etc. This property defines the configuration
    # and the default instantiation request of "DRBG" SecureRandom implementations
    # in the SUN provider. (Other DRBG implementations can also use this property.)
    # Applications can request different instantiation parameters like security
    # strength, capability, personalization string using one of the
    # getInstance(...,SecureRandomParameters,...) methods with a
    # DrbgParameters.Instantiation argument, but other settings such as the
    # mechanism and DRBG algorithm names are not currently configurable by any API.
    #
    # Please note that the SUN implementation of DRBG always supports reseeding.
    #
    # The value of this property is a comma-separated list of all configurable
    # aspects. The aspects can appear in any order but the same aspect can only
    # appear at most once. Its BNF-style definition is:

    # Properties to configure OCSP for certificate revocation checking
    #

    # Enable OCSP
    #
    # By default, OCSP is not used for certificate revocation checking.
    # This property enables the use of OCSP when set to the value "true".
    #
    # NOTE: SocketPermission is required to connect to an OCSP responder.
    #
    # Example,
    #   ocsp.enable=true

    #
    # Location of the OCSP responder
    #
    # By default, the location of the OCSP responder is determined implicitly
    # from the certificate being validated. This property explicitly specifies
    # the location of the OCSP responder. The property is used when the
    # Authority Information Access extension (defined in RFC 5280) is absent
    # from the certificate or when it requires overriding.
    #
    # Example,
    #   ocsp.responderURL=http://ocsp.example.net:80

    #
    # Subject name of the OCSP responder's certificate
    #
    # By default, the certificate of the OCSP responder is that of the issuer
    # of the certificate being validated. This property identifies the certificate
    # of the OCSP responder when the default does not apply. Its value is a string
    # distinguished name (defined in RFC 2253) which identifies a certificate in
    # the set of certificates supplied during cert path validation. In cases where
    # the subject name alone is not sufficient to uniquely identify the certificate
    # then both the "ocsp.responderCertIssuerName" and
    # "ocsp.responderCertSerialNumber" properties must be used instead. When this
    # property is set then those two properties are ignored.
    #
    # Example,
    #   ocsp.responderCertSubjectName=CN=OCSP Responder, O=XYZ Corp

    #
    # Issuer name of the OCSP responder's certificate
    #
    # By default, the certificate of the OCSP responder is that of the issuer
    # of the certificate being validated. This property identifies the certificate
    # of the OCSP responder when the default does not apply. Its value is a string
    # distinguished name (defined in RFC 2253) which identifies a certificate in
    # the set of certificates supplied during cert path validation. When this
    # property is set then the "ocsp.responderCertSerialNumber" property must also
    # be set. When the "ocsp.responderCertSubjectName" property is set then this
    # property is ignored.
    #
    # Example,
    #   ocsp.responderCertIssuerName=CN=Enterprise CA, O=XYZ Corp

    #
    # Serial number of the OCSP responder's certificate
    #
    # By default, the certificate of the OCSP responder is that of the issuer
    # of the certificate being validated. This property identifies the certificate
    # of the OCSP responder when the default does not apply. Its value is a string
    # of hexadecimal digits (colon or space separators may be present) which
    # identifies a certificate in the set of certificates supplied during cert path
    # validation. When this property is set then the "ocsp.responderCertIssuerName"
    # property must also be set. When the "ocsp.responderCertSubjectName" property
    # is set then this property is ignored.
    #
    # Example,
    #   ocsp.responderCertSerialNumber=2A:FF:00

    #
    # Policy for failed Kerberos KDC lookups:
    #
    # When a KDC is unavailable (network error, service failure, etc), it is
    # put inside a blacklist and accessed less often for future requests. The
    # value (case-insensitive) for this policy can be:
    #
    # tryLast
    #    KDCs in the blacklist are always tried after those not on the list.
    #
    # tryLess[:max_retries,timeout]
    #    KDCs in the blacklist are still tried by their order in the configuration,
    #    but with smaller max_retries and timeout values. max_retries and timeout
    #    are optional numerical parameters (default 1 and 5000, which means once
    #    and 5 seconds). Please notes that if any of the values defined here is
    #    more than what is defined in krb5.conf, it will be ignored.
    #
    # Whenever a KDC is detected as available, it is removed from the blacklist.
    # The blacklist is reset when krb5.conf is reloaded. You can add
    # refreshKrb5Config=true to a JAAS configuration file so that krb5.conf is
    # reloaded whenever a JAAS authentication is attempted.
    #
    # Example,
    #   krb5.kdc.bad.policy = tryLast
    #   krb5.kdc.bad.policy = tryLess:2,2000
    #
    krb5.kdc.bad.policy = tryLast

    # Kerberos cross-realm referrals (RFC 6806)
    #
    # OpenJDK's Kerberos client supports cross-realm referrals as defined in
    # RFC 6806. This allows to setup more dynamic environments in which clients
    # do not need to know in advance how to reach the realm of a target principal
    # (either a user or service).
    #
    # When a client issues an AS or a TGS request, the "canonicalize" option
    # is set to announce support of this feature. A KDC server may fulfill the
    # request or reply referring the client to a different one. If referred,
    # the client will issue a new request and the cycle repeats.
    #
    # In addition to referrals, the "canonicalize" option allows the KDC server
    # to change the client name in response to an AS request. For security reasons,
    # RFC 6806 (section 11) FAST scheme is enforced.
    #
    # Disable Kerberos cross-realm referrals. Value may be overwritten with a
    # System property (-Dsun.security.krb5.disableReferrals).
    sun.security.krb5.disableReferrals=false

    # Maximum number of AS or TGS referrals to avoid infinite loops. Value may
    # be overwritten with a System property (-Dsun.security.krb5.maxReferrals).
    sun.security.krb5.maxReferrals=5

    #
    # This property contains a list of disabled EC Named Curves that can be included
    # in the jdk.[tls|certpath|jar].disabledAlgorithms properties.  To include this
    # list in any of the disabledAlgorithms properties, add the property name as
    # an entry.

    # Algorithm restrictions for certification path (CertPath) processing

    # In some environments, certain algorithms or key lengths may be undesirable

    # generally no longer considered to be a secure hash algorithm.  This section
    # describes the mechanism for disabling algorithms based on algorithm name
    # and/or key length.  This includes algorithms used in certificates, as well
    # as revocation information such as CRLs and signed OCSP Responses.
    # The syntax of the disabled algorithm string is described as follows:
    #   DisabledAlgorithms:
    #       " DisabledAlgorithm { , DisabledAlgorithm } "
    #
    #   DisabledAlgorithm:
    #       AlgorithmName [Constraint] { '&' Constraint } | IncludeProperty
    #
    #   AlgorithmName:
    #       (see below)

    #       KeySizeConstraint | CAConstraint | DenyAfterConstraint |
    #       UsageConstraint

    #   KeySizeConstraint:
    #       keySize Operator KeyLength
    #
    #   Operator:
    #       <= | < | == | != | >= | >
    #
    #   KeyLength:
    #       Integer value of the algorithm's key length in bits
    #
    #   CAConstraint:
    #       jdkCA
    #
    #   DenyAfterConstraint:
    #       denyAfter YYYY-MM-DD
    #
    #   UsageConstraint:
    #       usage [TLSServer] [TLSClient] [SignedJAR]
    #
    #   IncludeProperty:
    #       include
    #
    # The "AlgorithmName" is the standard algorithm name of the disabled
    # algorithm. See the Java Security Standard Algorithm Names Specification
    # for information about Standard Algorithm Names.  Matching is
    # performed using a case-insensitive sub-element matching rule.  (For
    # example, in "SHA1withECDSA" the sub-elements are "SHA1" for hashing and
    # "ECDSA" for signatures.)  If the assertion "AlgorithmName" is a
    # sub-element of the certificate algorithm name, the algorithm will be
    # rejected during certification path building and validation.  For example,
    # the assertion algorithm name "DSA" will disable all certificate algorithms
    # that rely on DSA, such as NONEwithDSA, SHA1withDSA.  However, the assertion
    # will not disable algorithms related to "ECDSA".
    #
    # The "IncludeProperty" allows a implementation-defined security property that
    # can be included in the disabledAlgorithms properties.  These properties are
    # to help manage common actions easier across multiple disabledAlgorithm
    # properties.
    # There is one defined security property:  jdk.disabled.NamedCurves
    # See the property for more specific details.
    #
    #
    # A "Constraint" defines restrictions on the keys and/or certificates for
    # a specified AlgorithmName:
    #
    #   KeySizeConstraint:
    #     keySize Operator KeyLength
    #       The constraint requires a key of a valid size range if the
    #       "AlgorithmName" is of a key algorithm.  The "KeyLength" indicates
    #       the key size specified in number of bits.  For example,
    #       "RSA keySize <= 1024" indicates that any RSA key with key size less
    #       than or equal to 1024 bits should be disabled, and
    #       "RSA keySize < 1024, RSA keySize > 2048" indicates that any RSA key
    #       with key size less than 1024 or greater than 2048 should be disabled.
    #       This constraint is only used on algorithms that have a key size.
    #
    #   CAConstraint:
    #     jdkCA
    #       This constraint prohibits the specified algorithm only if the
    #       algorithm is used in a certificate chain that terminates at a marked
    #       trust anchor in the lib/security/cacerts keystore.  If the jdkCA
    #       constraint is not set, then all chains using the specified algorithm
    #       are restricted.  jdkCA may only be used once in a DisabledAlgorithm
    #       expression.
    #       Example:  To apply this constraint to SHA-1 certificates, include
    #       the following:  "SHA1 jdkCA"
    #
    #   DenyAfterConstraint:
    #     denyAfter YYYY-MM-DD
    #       This constraint prohibits a certificate with the specified algorithm
    #       from being used after the date regardless of the certificate's
    #       validity.  JAR files that are signed and timestamped before the
    #       constraint date with certificates containing the disabled algorithm
    #       will not be restricted.  The date is processed in the UTC timezone.
    #       This constraint can only be used once in a DisabledAlgorithm
    #       expression.
    #       Example:  To deny usage of RSA 2048 bit certificates after Feb 3 2020,
    #       use the following:  "RSA keySize == 2048 & denyAfter 2020-02-03"
    #
    #   UsageConstraint:
    #     usage [TLSServer] [TLSClient] [SignedJAR]
    #       This constraint prohibits the specified algorithm for
    #       a specified usage.  This should be used when disabling an algorithm
    #       for all usages is not practical. 'TLSServer' restricts the algorithm
    #       in TLS server certificate chains when server authentication is
    #       performed. 'TLSClient' restricts the algorithm in TLS client
    #       certificate chains when client authentication is performed.
    #       'SignedJAR' constrains use of certificates in signed jar files.
    #       The usage type follows the keyword and more than one usage type can
    #       be specified with a whitespace delimiter.
    #       Example:  "SHA1 usage TLSServer TLSClient"
    #
    # When an algorithm must satisfy more than one constraint, it must be
    # delimited by an ampersand '&'.  For example, to restrict certificates in a
    # chain that terminate at a distribution provided trust anchor and contain
    # RSA keys that are less than or equal to 1024 bits, add the following
    # constraint:  "RSA keySize <= 1024 & jdkCA".
    #
    # All DisabledAlgorithms expressions are processed in the order defined in the
    # property.  This requires lower keysize constraints to be specified
    # before larger keysize constraints of the same algorithm.  For example:
    # "RSA keySize < 1024 & jdkCA, RSA keySize < 2048".
    #
    # Note: The algorithm restrictions do not apply to trust anchors or
    # self-signed certificates.
    #
    # Note: This property is currently used by Oracle's PKIX implementation. It
    # is not guaranteed to be examined and used by other implementations.
    #
    # Example:
    #   jdk.certpath.disabledAlgorithms=MD2, DSA, RSA keySize < 2048
    #
    #
    jdk.certpath.disabledAlgorithms=MD2, MD5, SHA1 jdkCA & usage TLSServer, \

    # Algorithm restrictions for Secure Socket Layer/Transport Layer Security
    # (SSL/TLS/DTLS) processing
    #
    # In some environments, certain algorithms or key lengths may be undesirable
    # when using SSL/TLS/DTLS.  This section describes the mechanism for disabling
    # algorithms during SSL/TLS/DTLS security parameters negotiation, including
    # protocol version negotiation, cipher suites selection, named groups
    # selection, signature schemes selection, peer authentication and key
    # exchange mechanisms.
    #
    # Disabled algorithms will not be negotiated for SSL/TLS connections, even
    # if they are enabled explicitly in an application.
    #
    # For PKI-based peer authentication and key exchange mechanisms, this list
    # of disabled algorithms will also be checked during certification path
    # building and validation, including algorithms used in certificates, as
    # well as revocation information such as CRLs and signed OCSP Responses.
    # This is in addition to the jdk.certpath.disabledAlgorithms property above.
    #
    # See the specification of "jdk.certpath.disabledAlgorithms" for the

    #
    # Note: This property is currently used by the JDK Reference implementation.

    # Legacy algorithms for Secure Socket Layer/Transport Layer Security (SSL/TLS)
    # processing in JSSE implementation.
    #
    # In some environments, a certain algorithm may be undesirable but it
    # cannot be disabled because of its use in legacy applications.  Legacy
    # algorithms may still be supported, but applications should not use them
    # as the security strength of legacy algorithms are usually not strong enough
    # in practice.
    #
    # During SSL/TLS security parameters negotiation, legacy algorithms will
    # not be negotiated unless there are no other candidates.
    #
    # The syntax of the legacy algorithms string is described as this Java
    # BNF-style:
    #   LegacyAlgorithms:
    #       " LegacyAlgorithm { , LegacyAlgorithm } "
    #
    #   LegacyAlgorithm:
    #       AlgorithmName (standard JSSE algorithm name)
    #
    # See the specification of security property "jdk.certpath.disabledAlgorithms"
    # for the syntax and description of the "AlgorithmName" notation.
    #
    # Per SSL/TLS specifications, cipher suites have the form:
    #       SSL_KeyExchangeAlg_WITH_CipherAlg_MacAlg
    # or
    #       TLS_KeyExchangeAlg_WITH_CipherAlg_MacAlg
    #
    # For example, the cipher suite TLS_RSA_WITH_AES_128_CBC_SHA uses RSA as the
    # key exchange algorithm, AES_128_CBC (128 bits AES cipher algorithm in CBC
    # mode) as the cipher (encryption) algorithm, and SHA-1 as the message digest
    # algorithm for HMAC.
    #
    # The LegacyAlgorithm can be one of the following standard algorithm names:
    #     1. JSSE cipher suite name, e.g., TLS_RSA_WITH_AES_128_CBC_SHA
    #     2. JSSE key exchange algorithm name, e.g., RSA
    #     3. JSSE cipher (encryption) algorithm name, e.g., AES_128_CBC
    #     4. JSSE message digest algorithm name, e.g., SHA
    #
    # See SSL/TLS specifications and the Java Security Standard Algorithm Names
    # Specification for information about the algorithm names.
    #
    # Note: If a legacy algorithm is also restricted through the
    # jdk.tls.disabledAlgorithms property or the
    # java.security.AlgorithmConstraints API (See
    # javax.net.ssl.SSLParameters.setAlgorithmConstraints()),
    # then the algorithm is completely disabled and will not be negotiated.
    #
    # Note: This property is currently used by the JDK Reference implementation.
    # It is not guaranteed to be examined and used by other implementations.
    # There is no guarantee the property will continue to exist or be of the

    # negotiation mechanism is not used, the server offers the client group
    # parameters, base generator g and prime modulus p, for DHE key exchange.
    # It is recommended to use dynamic group parameters.  This property defines

    #       0 1 2 3 4 5 6 7 8 9 A B C D E F a b c d e f
    #
    # Whitespace characters are ignored.
    #
    # The "DefinedDHEParameters" defines the custom group parameters, prime
    # modulus p and base generator g, for a particular size of prime modulus p.
    # The "DHEPrimeModulus" defines the hexadecimal prime modulus p, and the
    # "DHEBaseGenerator" defines the hexadecimal base generator g of a group
    # parameter.  It is recommended to use safe primes for the custom group
    # parameters.
    #
    # If this property is not defined or the value is empty, the underlying JSSE

    # Cryptographic Jurisdiction Policy defaults
    #
    # Import and export control rules on cryptographic software vary from
    # country to country.  By default, Java provides two different sets of
    # cryptographic policy files[1]:
    #
    #     unlimited:  These policy files contain no restrictions on cryptographic
    #                 strengths or algorithms
    #
    #     limited:    These policy files contain more restricted cryptographic
    #                 strengths
    #
    # The default setting is determined by the value of the "crypto.policy"
    # Security property below. If your country or usage requires the
    # traditional restrictive policy, the "limited" Java cryptographic
    # policy is still available and may be appropriate for your environment.
    #
    # If you have restrictions that do not fit either use case mentioned
    # above, Java provides the capability to customize these policy files.
    # The "crypto.policy" security property points to a subdirectory
    # within /conf/security/policy/ which can be customized.

    # Serialization system-wide filter
    #
    # A filter, if configured, is used by java.io.ObjectInputStream during
    # deserialization to check the contents of the stream.
    # A filter is configured as a sequence of patterns, each pattern is either
    # matched against the name of a class in the stream or defines a limit.
    # Patterns are separated by ";" (semicolon).
    # Whitespace is significant and is considered part of the pattern.
    #
    # If the system property jdk.serialFilter is also specified, it supersedes
    # the security property value defined here.
    #
    # If a pattern includes a "=", it sets a limit.
    # If a limit appears more than once the last value is used.
    # Limits are checked before classes regardless of the order in the
    # sequence of patterns.
    # If any of the limits are exceeded, the filter status is REJECTED.
    #
    #   maxdepth=value - the maximum depth of a graph
    #   maxrefs=value  - the maximum number of internal references
    #   maxbytes=value - the maximum number of bytes in the input stream
    #   maxarray=value - the maximum array length allowed
    #
    # Other patterns, from left to right, match the class or package name as
    # returned from Class.getName.
    # If the class is an array type, the class or package to be matched is the
    # element type.
    # Arrays of any number of dimensions are treated the same as the element type.
    # For example, a pattern of "!example.Foo", rejects creation of any instance or
    # array of example.Foo.
    #
    # If the pattern starts with "!", the status is REJECTED if the remaining
    # pattern is matched; otherwise the status is ALLOWED if the pattern matches.
    # If the pattern contains "/", the non-empty prefix up to the "/" is the
    # module name;
    #   if the module name matches the module name of the class then
    #   the remaining pattern is matched with the class name.
    #   If there is no "/", the module name is not compared.
    # If the pattern ends with ".**" it matches any class in the package and all
    # subpackages.
    # If the pattern ends with ".*" it matches any class in the package.
    # If the pattern ends with "*", it matches any class with the pattern as a
    # prefix.

    # RMI Registry Serial Filter
    #
    # The filter pattern uses the same format as jdk.serialFilter.
    # This filter can override the builtin filter if additional types need to be
    # allowed or rejected from the RMI Registry or to decrease limits but not
    # to increase limits.
    # If the limits (maxdepth, maxrefs, or maxbytes) are exceeded, the object is rejected.
    #
    # Each non-array type is allowed or rejected if it matches one of the patterns,

    #
    # Array construction of any component type, including subarrays and arrays of

    #
    # The built-in filter allows subclasses of allowed classes and

    #
    # RMI Distributed Garbage Collector (DGC) Serial Filter
    #
    # The filter pattern uses the same format as jdk.serialFilter.
    # This filter can override the builtin filter if additional types need to be
    # allowed or rejected from the RMI DGC.
    #
    # Note: This property is currently used by the JDK Reference implementation.

    # JCEKS Encrypted Key Serial Filter
    #
    # This filter, if configured, is used by the JCEKS KeyStore during the
    # deserialization of the encrypted Key object stored inside a key entry.
    # If not configured or the filter result is UNDECIDED (i.e. none of the patterns
    # matches), the filter configured by jdk.serialFilter will be consulted.
    #
    # If the system property jceks.key.serialFilter is also specified, it supersedes
    # the security property value defined here.
    #
    # The filter pattern uses the same format as jdk.serialFilter. The default
    # pattern allows java.lang.Enum, java.security.KeyRep, java.security.KeyRep$Type,
    # and javax.crypto.spec.SecretKeySpec and rejects all the others.
    jceks.key.serialFilter = java.base/java.lang.Enum;java.base/java.security.KeyRep;\
      java.base/java.security.KeyRep$Type;java.base/javax.crypto.spec.SecretKeySpec;!*

    # The iteration count used for password-based encryption (PBE) in JCEKS
    # keystores. Values in the range 10000 to 5000000 are considered valid.
    # If the value is out of this range, or is not a number, or is unspecified;
    # a default of 200000 is used.
    #
    # If the system property jdk.jceks.iterationCount is also specified, it
    # supersedes the security property value defined here.
    #
    #jdk.jceks.iterationCount = 200000

    #
    # PKCS12 KeyStore properties
    #
    # The following properties, if configured, are used by the PKCS12 KeyStore
    # implementation during the creation of a new keystore. Several of the
    # properties may also be used when modifying an existing keystore. The
    # properties can be overridden by a KeyStore API that specifies its own
    # algorithms and parameters.
    #
    # If an existing PKCS12 keystore is loaded and then stored, the algorithm and
    # parameter used to generate the existing Mac will be reused. If the existing
    # keystore does not have a Mac, no Mac will be created while storing. If there
    # is at least one certificate in the existing keystore, the algorithm and
    # parameters used to encrypt the last certificate in the existing keystore will
    # be reused to encrypt all certificates while storing. If the last certificate
    # in the existing keystore is not encrypted, all certificates will be stored
    # unencrypted. If there is no certificate in the existing keystore, any newly
    # added certificate will be encrypted (or stored unencrypted if algorithm
    # value is "NONE") using the "keystore.pkcs12.certProtectionAlgorithm" and
    # "keystore.pkcs12.certPbeIterationCount" values defined here. Existing private
    # and secret key(s) are not changed. Newly set private and secret key(s) will
    # be encrypted using the "keystore.pkcs12.keyProtectionAlgorithm" and
    # "keystore.pkcs12.keyPbeIterationCount" values defined here.
    #
    # In order to apply new algorithms and parameters to all entries in an
    # existing keystore, one can create a new keystore and add entries in the
    # existing keystore into the new keystore. This can be achieved by calling the
    # "keytool -importkeystore" command.
    #
    # If a system property of the same name is also specified, it supersedes the
    # security property value defined here.
    #
    # If the property is set to an illegal value,
    # an iteration count that is not a positive integer, or an unknown algorithm
    # name, an exception will be thrown when the property is used.
    # If the property is not set or empty, a default value will be used.
    #
    # Note: These properties are currently used by the JDK Reference implementation.
    # They are not guaranteed to be examined and used by other implementations.

    # The algorithm used to encrypt a certificate. This can be any non-Hmac PBE
    # algorithm defined in the Cipher section of the Java Security Standard
    # Algorithm Names Specification. When set to "NONE", the certificate
    # is not encrypted. The default value is "PBEWithHmacSHA256AndAES_256".
    #keystore.pkcs12.certProtectionAlgorithm = PBEWithHmacSHA256AndAES_256

    # The iteration count used by the PBE algorithm when encrypting a certificate.
    # This value must be a positive integer. The default value is 10000.
    #keystore.pkcs12.certPbeIterationCount = 10000

    # The algorithm used to encrypt a private key or secret key. This can be
    # any non-Hmac PBE algorithm defined in the Cipher section of the Java
    # Security Standard Algorithm Names Specification. The value must not be "NONE".
    # The default value is "PBEWithHmacSHA256AndAES_256".
    #keystore.pkcs12.keyProtectionAlgorithm = PBEWithHmacSHA256AndAES_256

    # The iteration count used by the PBE algorithm when encrypting a private key
    # or a secret key. This value must be a positive integer. The default value
    # is 10000.
    #keystore.pkcs12.keyPbeIterationCount = 10000

    # The algorithm used to calculate the optional MacData at the end of a PKCS12
    # file. This can be any HmacPBE algorithm defined in the Mac section of the
    # Java Security Standard Algorithm Names Specification. When set to "NONE",
    # no Mac is generated. The default value is "HmacPBESHA256".
    #keystore.pkcs12.macAlgorithm = HmacPBESHA256

    # The iteration count used by the MacData algorithm. This value must be a
    # positive integer. The default value is 10000.
    #keystore.pkcs12.macIterationCount = 10000

    #
    # Enhanced exception message information
    #
    # By default, exception messages should not include potentially sensitive
    # information such as file names, host names, or port numbers. This property
    # accepts one or more comma separated values, each of which represents a
    # category of enhanced exception message information to enable. Values are
    # case-insensitive. Leading and trailing whitespaces, surrounding each value,
    # are ignored. Unknown values are ignored.
    #
    # NOTE: Use caution before setting this property. Setting this property
    # exposes sensitive information in Exceptions, which could, for example,
    # propagate to untrusted code or be emitted in stack traces that are
    # inadvertently disclosed and made accessible over a public network.
    #
    # The categories are:
    #
    #  hostInfo - IOExceptions thrown by java.net.Socket and the socket types in the
    #             java.nio.channels package will contain enhanced exception
    #             message information
    #
    #  jar      - enables more detailed information in the IOExceptions thrown
    #             by classes in the java.util.jar package
    #
    # The property setting in this file can be overridden by a system property of
    # the same name, with the same syntax and possible values.
    #
    #jdk.includeInExceptions=hostInfo,jar

    #
    # Disabled mechanisms for the Simple Authentication and Security Layer (SASL)
    #
    # Disabled mechanisms will not be negotiated by both SASL clients and servers.
    # These mechanisms will be ignored if they are specified in the "mechanisms"
    # argument of "Sasl.createSaslClient" or the "mechanism" argument of
    # "Sasl.createSaslServer".
    #
    # The value of this property is a comma-separated list of SASL mechanisms.
    # The mechanisms are case-sensitive. Whitespaces around the commas are ignored.
    #
    # Note: This property is currently used by the JDK Reference implementation.
    # It is not guaranteed to be examined and used by other implementations.
    #
    # Example:
    #   jdk.sasl.disabledMechanisms=PLAIN, CRAM-MD5, DIGEST-MD5
    jdk.sasl.disabledMechanisms=

    #
    # Policies for distrusting Certificate Authorities (CAs).
    #
    # This is a comma separated value of one or more case-sensitive strings, each
    # of which represents a policy for determining if a CA should be distrusted.
    # The supported values are:
    #
    #   SYMANTEC_TLS : Distrust TLS Server certificates anchored by a Symantec
    #   root CA and issued after April 16, 2019 unless issued by one of the
    #   following subordinate CAs which have a later distrust date:
    #     1. Apple IST CA 2 - G1, SHA-256 fingerprint:
    #        AC2B922ECFD5E01711772FEA8ED372DE9D1E2245FCE3F57A9CDBEC77296A424B
    #        Distrust after December 31, 2019.
    #     2. Apple IST CA 8 - G1, SHA-256 fingerprint:
    #        A4FE7C7F15155F3F0AEF7AAA83CF6E06DEB97CA3F909DF920AC1490882D488ED
    #        Distrust after December 31, 2019.
    #
    # Leading and trailing whitespace surrounding each value are ignored.
    # Unknown values are ignored. If the property is commented out or set to the
    # empty String, no policies are enforced.
    #
    # Note: This property is currently used by the JDK Reference implementation.
    # It is not guaranteed to be supported by other SE implementations. Also, this
    # property does not override other security properties which can restrict
    # certificates such as jdk.tls.disabledAlgorithms or
    # jdk.certpath.disabledAlgorithms; those restrictions are still enforced even
    # if this property is not enabled.
    #
    jdk.security.caDistrustPolicies=SYMANTEC_TLS

    #
    # FilePermission path canonicalization
    #
    # This security property dictates how the path argument is processed and stored
    # while constructing a FilePermission object. If the value is set to true, the
    # path argument is canonicalized and FilePermission methods (such as implies,
    # equals, and hashCode) are implemented based on this canonicalized result.
    # Otherwise, the path argument is not canonicalized and FilePermission methods are
    # implemented based on the original input. See the implementation note of the
    # FilePermission class for more details.
    #
    # If a system property of the same name is also specified, it supersedes the
    # security property value defined here.
    #
    # The default value for this property is false.
    #
    jdk.io.permissionsUseCanonicalPath=false

    #
    # Policies for the proxy_impersonator Kerberos ccache configuration entry
    #
    # The proxy_impersonator ccache configuration entry indicates that the ccache
    # is a synthetic delegated credential for use with S4U2Proxy by an intermediate
    # server. The ccache file should also contain the TGT of this server and
    # an evidence ticket from the default principal of the ccache to this server.
    #
    # This security property determines how Java uses this configuration entry.
    # There are 3 possible values:
    #
    #  no-impersonate     - Ignore this configuration entry, and always act as
    #                       the owner of the TGT (if it exists).
    #
    #  try-impersonate    - Try impersonation when this configuration entry exists.
    #                       If no matching TGT or evidence ticket is found,
    #                       fallback to no-impersonate.
    #
    #  always-impersonate - Always impersonate when this configuration entry exists.
    #                       If no matching TGT or evidence ticket is found,
    #                       no initial credential is read from the ccache.
    #
    # The default value is "always-impersonate".
    #
    # If a system property of the same name is also specified, it supersedes the
    # security property value defined here.
    #
    #jdk.security.krb5.default.initiate.credential=always-impersonate

    #
    # Trust Anchor Certificates - CA Basic Constraint check
    #
    # X.509 v3 certificates used as Trust Anchors (to validate signed code or TLS
    # connections) must have the cA Basic Constraint field set to 'true'. Also, if
    # they include a Key Usage extension, the keyCertSign bit must be set. These
    # checks, enabled by default, can be disabled for backward-compatibility
    # purposes with the jdk.security.allowNonCaAnchor System and Security
    # properties. In the case that both properties are simultaneously set, the
    # System value prevails. The default value of the property is "false".
    #
    #jdk.security.allowNonCaAnchor=true

    #
    # The default Character set name (java.nio.charset.Charset.forName())
    # for converting TLS ALPN values between byte arrays and Strings.
    # Prior versions of the JDK may use UTF-8 as the default charset. If
    # you experience interoperability issues, setting this property to UTF-8
    # may help.
    #
    # jdk.tls.alpnCharset=UTF-8
    jdk.tls.alpnCharset=ISO_8859_1

    #
    # JNDI Object Factories Filter
    #
    # This filter is used by the JNDI runtime to control the set of object factory classes
    # which will be allowed to instantiate objects from object references returned by
    # naming/directory systems. The factory class named by the reference instance will be
    # matched against this filter. The filter property supports pattern-based filter syntax
    # with the same format as jdk.serialFilter.
    #
    # Each pattern is matched against the factory class name to allow or disallow it's
    # instantiation. The access to a factory class is allowed unless the filter returns
    # REJECTED.
    #
    # Note: This property is currently used by the JDK Reference implementation.
    # It is not guaranteed to be examined and used by other implementations.
    #
    # If the system property jdk.jndi.object.factoriesFilter is also specified, it supersedes
    # the security property value defined here. The default value of the property is "*".
    #
    # The default pattern value allows any object factory class specified by the reference
    # instance to recreate the referenced object.
    #jdk.jndi.object.factoriesFilter=*
