   2 # This is the "master security properties file".
   3 #
   4 # An alternate java.security properties file may be specified
   5 # from the command line via the system property
   6 #
   7 #    -Djava.security.properties=<URL>
   8 #
   9 # This properties file appends to the master security properties file.
  10 # If both properties files specify values for the same key, the value
  11 # from the command-line properties file is selected, as it is the last
  12 # one loaded.
  13 #
  14 # Also, if you specify
  15 #
  16 #    -Djava.security.properties==<URL> (2 equals),
  17 #
  18 # then that properties file completely overrides the master security
  19 # properties file.
  20 #
  21 # To disable the ability to specify an additional properties file from
  22 # the command line, set the key security.overridePropertiesFile
  23 # to false in the master security properties file. It is set to true
  24 # by default.
  25 
  26 # In this file, various security properties are set for use by
  27 # java.security classes. This is where users can statically register
  28 # Cryptography Package Providers ("providers" for short). The term
  29 # "provider" refers to a package or set of packages that supply a
  30 # concrete implementation of a subset of the cryptography aspects of
  31 # the Java Security API. A provider may, for example, implement one or
  32 # more digital signature algorithms or message digest algorithms.
  33 #
  34 # Each provider must implement a subclass of the Provider class.
  35 # To register a provider in this master security properties file,
  36 # specify the Provider subclass name and priority in the format
  37 #
  38 #    security.provider.<n>=<className>
  39 #
  40 # This declares a provider, and specifies its preference
  41 # order n. The preference order is the order in which providers are
  42 # searched for requested algorithms (when no specific provider is
  43 # requested). The order is 1-based; 1 is the most preferred, followed
  44 # by 2, and so on.
  45 #
  46 # <className> must specify the subclass of the Provider class whose
  47 # constructor sets the values of various properties that are required
  48 # for the Java Security API to look up the algorithms or other
  49 # facilities implemented by the provider.
  50 #
  51 # There must be at least one provider specification in java.security.
  52 # There is a default provider that comes standard with the JDK. It
  53 # is called the "SUN" provider, and its Provider subclass
  54 # named Sun appears in the sun.security.provider package. Thus, the
  55 # "SUN" provider is registered via the following:
  56 #
  57 #    security.provider.1=sun.security.provider.Sun
  58 #
  59 # (The number 1 is used for the default provider.)
  60 #
  61 # Note: Providers can be dynamically registered instead by calls to
  62 # either the addProvider or insertProviderAt method in the Security
  63 # class.
  64 
  65 #
  66 # List of providers and their preference orders (see above):

  72 security.provider.5=com.sun.crypto.provider.SunJCE
  73 security.provider.6=sun.security.jgss.SunProvider
  74 security.provider.7=com.sun.security.sasl.Provider
  75 security.provider.8=org.jcp.xml.dsig.internal.dom.XMLDSigRI

  80 # Sun Provider SecureRandom seed source.
  81 #
  82 # Select the primary source of seed data for the "SHA1PRNG" and
  83 # "NativePRNG" SecureRandom implementations in the "Sun" provider.
  84 # (Other SecureRandom implementations might also use this property.)
  85 #
  86 # On Unix-like systems (for example, Solaris/Linux/MacOS), the
  87 # "NativePRNG" and "SHA1PRNG" implementations obtains seed data from
  88 # special device files such as file:/dev/random.
  89 #
  90 # On Windows systems, specifying the URLs "file:/dev/random" or
  91 # "file:/dev/urandom" will enable the native Microsoft CryptoAPI seeding
  92 # mechanism for SHA1PRNG.
  93 #
  94 # By default, an attempt is made to use the entropy gathering device
  95 # specified by the "securerandom.source" Security property.  If an
  96 # exception occurs while accessing the specified URL:
  97 #
  98 #     SHA1PRNG:
  99 #         the traditional system/thread activity algorithm will be used.
 100 #
 101 #     NativePRNG:
 102 #         a default value of /dev/random will be used.  If neither
 103 #         are available, the implementation will be disabled.
 104 #         "file" is the only currently supported protocol type.
 105 #
 106 # The entropy gathering device can also be specified with the System
 107 # property "java.security.egd". For example:
 108 #
 109 #   % java -Djava.security.egd=file:/dev/random MainClass
 110 #
 111 # Specifying this System property will override the
 112 # "securerandom.source" Security property.
 113 #
 114 # In addition, if "file:/dev/random" or "file:/dev/urandom" is
 115 # specified, the "NativePRNG" implementation will be more preferred than
 116 # SHA1PRNG in the Sun provider.

 342 # Location of the OCSP responder
 343 #
 344 # By default, the location of the OCSP responder is determined implicitly

 350 # Example,
 351 #   ocsp.responderURL=http://ocsp.example.net:80
 352 
 353 #
 354 # Subject name of the OCSP responder's certificate
 355 #
 356 # By default, the certificate of the OCSP responder is that of the issuer
 357 # of the certificate being validated. This property identifies the certificate
 358 # of the OCSP responder when the default does not apply. Its value is a string
 359 # distinguished name (defined in RFC 2253) which identifies a certificate in
 360 # the set of certificates supplied during cert path validation. In cases where
 361 # the subject name alone is not sufficient to uniquely identify the certificate
 362 # then both the "ocsp.responderCertIssuerName" and
 363 # "ocsp.responderCertSerialNumber" properties must be used instead. When this
 364 # property is set then those two properties are ignored.
 365 #
 366 # Example,
 367 #   ocsp.responderCertSubjectName="CN=OCSP Responder, O=XYZ Corp"
 368 
 369 #
 370 # Issuer name of the OCSP responder's certificate

 377 # property is set then the "ocsp.responderCertSerialNumber" property must also
 378 # be set. When the "ocsp.responderCertSubjectName" property is set then this
 379 # property is ignored.
 380 #
 381 # Example,
 382 #   ocsp.responderCertIssuerName="CN=Enterprise CA, O=XYZ Corp"
 383 
 384 #
 385 # Serial number of the OCSP responder's certificate
 386 #
 387 # By default, the certificate of the OCSP responder is that of the issuer
 388 # of the certificate being validated. This property identifies the certificate
 389 # of the OCSP responder when the default does not apply. Its value is a string
 390 # of hexadecimal digits (colon or space separators may be present) which
 391 # identifies a certificate in the set of certificates supplied during cert path
 392 # validation. When this property is set then the "ocsp.responderCertIssuerName"
 393 # property must also be set. When the "ocsp.responderCertSubjectName" property
 394 # is set then this property is ignored.

 400 # Policy for failed Kerberos KDC lookups:
 401 #
 402 # When a KDC is unavailable (network error, service failure, etc), it is
 403 # put inside a blacklist and accessed less often for future requests. The
 404 # value (case-insensitive) for this policy can be:
 405 #
 406 # tryLast
 407 #    KDCs in the blacklist are always tried after those not on the list.
 408 #
 409 # tryLess[:max_retries,timeout]
 410 #    KDCs in the blacklist are still tried by their order in the configuration,
 411 #    but with smaller max_retries and timeout values. max_retries and timeout
 412 #    are optional numerical parameters (default 1 and 5000, which means once
 413 #    and 5 seconds). Please notes that if any of the values defined here is
 414 #    more than what is defined in krb5.conf, it will be ignored.
 415 #
 416 # Whenever a KDC is detected as available, it is removed from the blacklist.
 417 # The blacklist is reset when krb5.conf is reloaded. You can add
 418 # refreshKrb5Config=true to a JAAS configuration file so that krb5.conf is
 419 # reloaded whenever a JAAS authentication is attempted.
 420 #
 421 # Example,
 422 #   krb5.kdc.bad.policy = tryLast
 423 #   krb5.kdc.bad.policy = tryLess:2,2000
 424 krb5.kdc.bad.policy = tryLast

 426 # Algorithm restrictions for certification path (CertPath) processing

 438 #   DisabledAlgorithm:
 439 #       AlgorithmName [Constraint] { '&' Constraint }

 450 #
 451 #   Operator:
 452 #       <= | < | == | != | >= | >
 453 #
 454 #   KeyLength:
 455 #       Integer value of the algorithm's key length in bits
 456 #
 457 #   CAConstraint:

 462 #
 463 #   UsageConstraint:
 464 #       usage [TLSServer] [TLSClient] [SignedJAR]
 465 #
 466 # The "AlgorithmName" is the standard algorithm name of the disabled
 467 # algorithm. See "Java Cryptography Architecture Standard Algorithm Name
 468 # Documentation" for information about Standard Algorithm Names.  Matching
 469 # is performed using a case-insensitive sub-element matching rule.  (For
 470 # example, in "SHA1withECDSA" the sub-elements are "SHA1" for hashing and
 471 # "ECDSA" for signatures.)  If the assertion "AlgorithmName" is a
 472 # sub-element of the certificate algorithm name, the algorithm will be
 473 # rejected during certification path building and validation.  For example,
 474 # the assertion algorithm name "DSA" will disable all certificate algorithms
 475 # that rely on DSA, such as NONEwithDSA, SHA1withDSA.  However, the assertion
 476 # will not disable algorithms related to "ECDSA".
 477 #
 478 # A "Constraint" defines restrictions on the keys and/or certificates for
 479 # a specified AlgorithmName:
 480 #
 481 #   KeySizeConstraint:
 482 #     keySize Operator KeyLength
 483 #       The constraint requires a key of a valid size range if the
 484 #       "AlgorithmName" is of a key algorithm.  The "KeyLength" indicates
 485 #       the key size specified in number of bits.  For example,
 486 #       "RSA keySize <= 1024" indicates that any RSA key with key size less
 487 #       than or equal to 1024 bits should be disabled, and
 488 #       "RSA keySize < 1024, RSA keySize > 2048" indicates that any RSA key
 489 #       with key size less than 1024 or greater than 2048 should be disabled.
 490 #       This constraint is only used on algorithms that have a key size.
 491 #
 492 #   CAConstraint:
 493 #     jdkCA
 494 #       This constraint prohibits the specified algorithm only if the
 495 #       algorithm is used in a certificate chain that terminates at a marked
 496 #       trust anchor in the lib/security/cacerts keystore.  If the jdkCA
 497 #       constraint is not set, then all chains using the specified algorithm
 498 #       are restricted.  jdkCA may only be used once in a DisabledAlgorithm
 499 #       expression.
 500 #       Example:  To apply this constraint to SHA-1 certificates, include
 501 #       the following:  "SHA1 jdkCA"
 502 #
 503 #   DenyAfterConstraint:
 504 #     denyAfter YYYY-MM-DD
 505 #       This constraint prohibits a certificate with the specified algorithm
 506 #       from being used after the date regardless of the certificate's
 507 #       validity.  JAR files that are signed and timestamped before the
 508 #       constraint date with certificates containing the disabled algorithm
 509 #       will not be restricted.  The date is processed in the UTC timezone.
 510 #       This constraint can only be used once in a DisabledAlgorithm
 511 #       expression.
 512 #       Example:  To deny usage of RSA 2048 bit certificates after Feb 3 2020,
 513 #       use the following:  "RSA keySize == 2048 & denyAfter 2020-02-03"
 514 #
 515 #   UsageConstraint:
 516 #     usage [TLSServer] [TLSClient] [SignedJAR]
 517 #       This constraint prohibits the specified algorithm for
 518 #       a specified usage.  This should be used when disabling an algorithm
 519 #       for all usages is not practical. 'TLSServer' restricts the algorithm
 520 #       in TLS server certificate chains when server authentication is
 521 #       performed. 'TLSClient' restricts the algorithm in TLS client
 522 #       certificate chains when client authentication is performed.
 523 #       'SignedJAR' constrains use of certificates in signed jar files.
 524 #       The usage type follows the keyword and more than one usage type can
 525 #       be specified with a whitespace delimiter.
 526 #       Example:  "SHA1 usage TLSServer TLSClient"
 527 #
 528 # When an algorithm must satisfy more than one constraint, it must be
 529 # delimited by an ampersand '&'.  For example, to restrict certificates in a
 530 # chain that terminate at a distribution provided trust anchor and contain
 531 # RSA keys that are less than or equal to 1024 bits, add the following
 532 # constraint:  "RSA keySize <= 1024 & jdkCA".
 533 #
 534 # All DisabledAlgorithms expressions are processed in the order defined in the
 535 # property.  This requires lower keysize constraints to be specified
 536 # before larger keysize constraints of the same algorithm.  For example:
 537 # "RSA keySize < 1024 & jdkCA, RSA keySize < 2048".
 538 #
 539 # Note: The algorithm restrictions do not apply to trust anchors or
 540 # self-signed certificates.
 541 #
 542 # Note: This property is currently used by Oracle's PKIX implementation. It
 543 # is not guaranteed to be examined and used by other implementations.
 544 #
 545 # Example:
 546 #   jdk.certpath.disabledAlgorithms=MD2, DSA, RSA keySize < 2048
 547 #

 554 #
 555 # In some environments, certain algorithms or key lengths may be undesirable

 596 # Algorithm restrictions for Secure Socket Layer/Transport Layer Security
 597 # (SSL/TLS) processing
 598 #
 599 # In some environments, certain algorithms or key lengths may be undesirable
 600 # when using SSL/TLS.  This section describes the mechanism for disabling
 601 # algorithms during SSL/TLS security parameters negotiation, including
 602 # protocol version negotiation, cipher suites selection, peer authentication
 603 # and key exchange mechanisms.
 604 #
 605 # Disabled algorithms will not be negotiated for SSL/TLS connections, even
 606 # if they are enabled explicitly in an application.
 607 #
 608 # For PKI-based peer authentication and key exchange mechanisms, this list
 609 # of disabled algorithms will also be checked during certification path
 610 # building and validation, including algorithms used in certificates, as
 611 # well as revocation information such as CRLs and signed OCSP Responses.
 612 # This is in addition to the jdk.certpath.disabledAlgorithms property above.

 628 # Legacy algorithms for Secure Socket Layer/Transport Layer Security (SSL/TLS)
 629 # processing in JSSE implementation.
 630 #
 631 # In some environments, a certain algorithm may be undesirable but it
 632 # cannot be disabled because of its use in legacy applications.  Legacy
 633 # algorithms may still be supported, but applications should not use them
 634 # as the security strength of legacy algorithms are usually not strong enough
 635 # in practice.
 636 #
 637 # During SSL/TLS security parameters negotiation, legacy algorithms will
 638 # not be negotiated unless there are no other candidates.
 639 #
 640 # The syntax of the legacy algorithms string is described as this Java
 641 # BNF-style:
 642 #   LegacyAlgorithms:
 643 #       " LegacyAlgorithm { , LegacyAlgorithm } "
 644 #
 645 #   LegacyAlgorithm:

 647 #
 648 # See the specification of security property "jdk.certpath.disabledAlgorithms"
 649 # for the syntax and description of the "AlgorithmName" notation.
 650 #
 651 # Per SSL/TLS specifications, cipher suites have the form:
 652 #       SSL_KeyExchangeAlg_WITH_CipherAlg_MacAlg
 653 # or
 654 #       TLS_KeyExchangeAlg_WITH_CipherAlg_MacAlg
 655 #
 656 # For example, the cipher suite TLS_RSA_WITH_AES_128_CBC_SHA uses RSA as the
 657 # key exchange algorithm, AES_128_CBC (128 bits AES cipher algorithm in CBC
 658 # mode) as the cipher (encryption) algorithm, and SHA-1 as the message digest
 659 # algorithm for HMAC.
 660 #
 661 # The LegacyAlgorithm can be one of the following standard algorithm names:
 662 #     1. JSSE cipher suite name, e.g., TLS_RSA_WITH_AES_128_CBC_SHA
 663 #     2. JSSE key exchange algorithm name, e.g., RSA
 664 #     3. JSSE cipher (encryption) algorithm name, e.g., AES_128_CBC
 665 #     4. JSSE message digest algorithm name, e.g., SHA

 711 #
 712 # Whitespace characters are ignored.
 713 #
 714 # The "DefinedDHEParameters" defines the custom group parameters, prime

 716 # The "DHEPrimeModulus" defines the hexadecimal prime modulus p, and the

 720 #
 721 # If this property is not defined or the value is empty, the underlying JSSE

 741 # Cryptographic Jurisdiction Policy defaults
 742 #
 743 # Import and export control rules on cryptographic software vary from
 744 # country to country.  By default, the JDK provides two different sets of
 745 # cryptographic policy files:
 746 #
 747 #     unlimited:  These policy files contain no restrictions on cryptographic
 748 #                 strengths or algorithms.
 749 #
 750 #     limited:    These policy files contain more restricted cryptographic
 751 #                 strengths, and are still available if your country or
 752 #                 usage requires the traditional restrictive policy.
 753 #
 754 # The JDK JCE framework uses the unlimited policy files by default.
 755 # However the user may explicitly choose a set either by defining the
 756 # "crypto.policy" Security property or by installing valid JCE policy
 757 # jar files into the traditional JDK installation location.  To better
 758 # support older JDK Update releases, the "crypto.policy" property is not
 759 # defined by default.  See below for more information.
 760 #
 761 # The following logic determines which policy files are used:
 762 #
 763 #         <java-home> refers to the directory where the JRE was
 764 #         installed and may be determined using the "java.home"
 765 #         System property.
 766 #
 767 # 1.  If the Security property "crypto.policy" has been defined,
 768 #     then the following mechanism is used:
 769 #
 770 #     The policy files are stored as jar files in subdirectories of
 771 # <java-home>/lib/security/policy.  Each directory contains a complete
 772 # set of policy files.
 773 #
 774 #     The "crypto.policy" Security property controls the directory
 775 #     selection, and thus the effective cryptographic policy.
 776 #
 777 # The default set of directories is:
 778 #
 779 #     limited | unlimited
 780 #
 781 # 2.  If the "crypto.policy" property is not set and the traditional
 782 #     US_export_policy.jar and local_policy.jar files
 783 #     (e.g. limited/unlimited) are found in the legacy
 784 #     <java-home>/lib/security directory, then the rules embedded within
 785 #     those jar files will be used. This helps preserve compatibility
 786 # for users upgrading from an older installation.
 787 #
 788 # 3.  If the jar files are not present in the legacy location
 789 #     and the "crypto.policy" Security property is not defined,
 790 #     then the JDK will use the unlimited settings (equivalent to
 791 #     crypto.policy=unlimited)
 792 #
 793 # Please see the JCA documentation for additional information on these
 794 # files and formats.

 859 #
 860 # A filter, if configured, is used by java.io.ObjectInputStream during
 861 # deserialization to check the contents of the stream.
 862 # A filter is configured as a sequence of patterns, each pattern is either
 863 # matched against the name of a class in the stream or defines a limit.

 865 # Whitespace is significant and is considered part of the pattern.
 866 #
 867 # If the system property jdk.serialFilter is also specified, it supersedes
 868 # the security property value defined here.
 869 #
 870 # If a pattern includes a "=", it sets a limit.
 871 # If a limit appears more than once the last value is used.
 872 # Limits are checked before classes regardless of the order in the sequence of patterns.
 873 # If any of the limits are exceeded, the filter status is REJECTED.
 874 #
 875 #   maxdepth=value - the maximum depth of a graph
 876 #   maxrefs=value  - the maximum number of internal references
 877 #   maxbytes=value - the maximum number of bytes in the input stream
 878 #   maxarray=value - the maximum array length allowed
 879 #
 880 # Other patterns, from left to right, match the class or package name as
 881 # returned from Class.getName.
 882 # If the class is an array type, the class or package to be matched is the element type.
 883 # Arrays of any number of dimensions are treated the same as the element type.
 884 # For example, a pattern of "!example.Foo", rejects creation of any instance or
 885 # array of example.Foo.
 886 #
 887 # If the pattern starts with "!", the status is REJECTED if the remaining pattern
 888 #   is matched; otherwise the status is ALLOWED if the pattern matches.
 889 # If the pattern ends with ".**" it matches any class in the package and all subpackages.

 898 # RMI Registry Serial Filter
 899 #
 900 # The filter pattern uses the same format as jdk.serialFilter.
 901 # This filter can override the builtin filter if additional types need to be
 902 # allowed or rejected from the RMI Registry or to decrease limits but not
 903 # to increase limits.
 904 # If the limits (maxdepth, maxrefs, or maxbytes) are exceeded, the object is rejected.
 905 #
 906 # Each non-array type is allowed or rejected if it matches one of the patterns,
 907 # evaluated from left to right, and is otherwise allowed. Arrays of any
 908 # component type, including subarrays and arrays of primitives, are allowed.
 909 #
 910 # Array construction of any component type, including subarrays and arrays of
 911 # primitives, are allowed unless the length is greater than the maxarray limit.
 912 # The filter is applied to each array element.
 913 #
 914 # The built-in filter allows subclasses of allowed classes and
 915 # can approximately be represented as the pattern:
 916 #
 917 #sun.rmi.registry.registryFilter=\
 918 #    maxarray=1000000;\
 919 #    maxdepth=20;\
 920 #    java.lang.String;\

 930 # RMI Distributed Garbage Collector (DGC) Serial Filter
 931 #
 932 # The filter pattern uses the same format as jdk.serialFilter.
 933 # This filter can override the builtin filter if additional types need to be
 934 # allowed or rejected from the RMI DGC.
 935 #
 936 # The builtin DGC filter can approximately be represented as the filter pattern:
 937 #
 938 #sun.rmi.transport.dgcFilter=\
 939 #    java.rmi.server.ObjID;\
 940 #    java.rmi.server.UID;\
 941 #    java.rmi.dgc.VMID;\
 942 #    java.rmi.dgc.Lease;\

 945 # CORBA ORBIorTypeCheckRegistryFilter
 946 # Type check enhancement for ORB::string_to_object processing
 947 #
 948 # An IOR type check filter, if configured, is used by an ORB during
 949 # an ORB::string_to_object invocation to check the veracity of the type encoded
 950 # in the ior string.
 951 #
 952 # The filter pattern consists of a semi-colon separated list of class names.
 953 # The configured list contains the binary class names of the IDL interface types
 954 # corresponding to the IDL stub class to be instantiated.
 955 # As such, a filter specifies a list of IDL stub classes that will be
 956 # allowed by an ORB when an ORB::string_to_object is invoked.
 957 # It is used to specify a white list configuration of acceptable
 958 # IDL stub types which may be contained in a stringified IOR
 959 # parameter passed as input to an ORB::string_to_object method.

 962 # It is not guaranteed to be examined and used by other implementations.

 967 # JCEKS Encrypted Key Serial Filter
 968 #
 969 # This filter, if configured, is used by the JCEKS KeyStore during the
 970 # deserialization of the encrypted Key object stored inside a key entry.
 971 # If not configured or the filter result is UNDECIDED (i.e. none of the patterns
 972 # matches), the filter configured by jdk.serialFilter will be consulted.
 973 #
 974 # If the system property jceks.key.serialFilter is also specified, it supersedes
 975 # the security property value defined here.
 976 #
 977 # The filter pattern uses the same format as jdk.serialFilter. The default
 978 # pattern allows java.lang.Enum, java.security.KeyRep, java.security.KeyRep$Type,
 979 # and javax.crypto.spec.SecretKeySpec and rejects all the others.
