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.

402 #
403 # By default, the location of the OCSP responder is determined implicitly

411
412 #
413 # Subject name of the OCSP responder's certificate
414 #
415 # By default, the certificate of the OCSP responder is that of the issuer
416 # of the certificate being validated. This property identifies the certificate
417 # of the OCSP responder when the default does not apply. Its value is a string

420 # the subject name alone is not sufficient to uniquely identify the certificate
421 # then both the "ocsp.responderCertIssuerName" and
422 # "ocsp.responderCertSerialNumber" properties must be used instead. When this
423 # property is set then those two properties are ignored.
424 #
425 # Example,

427
428 #
429 # Issuer name of the OCSP responder's certificate
430 #
431 # By default, the certificate of the OCSP responder is that of the issuer

438 # property is ignored.
439 #
440 # Example,
441 # ocsp.responderCertIssuerName="CN=Enterprise CA, O=XYZ Corp"

443 #
444 # Serial number of the OCSP responder's certificate
445 #
446 # By default, the certificate of the OCSP responder is that of the issuer

448 # of the OCSP responder when the default does not apply. Its value is a string
449 # of hexadecimal digits (colon or space separators may be present) which
450 # identifies a certificate in the set of certificates supplied during cert path
451 # validation. When this property is set then the "ocsp.responderCertIssuerName"
452 # property must also be set. When the "ocsp.responderCertSubjectName" property
453 # is set then this property is ignored.

463 # value (case-insensitive) for this policy can be:
464 #
465 # tryLast
466 # KDCs in the blacklist are always tried after those not on the list.
467 #
468 # tryLess[:max_retries,timeout]
469 # KDCs in the blacklist are still tried by their order in the configuration,
470 # but with smaller max_retries and timeout values. max_retries and timeout
471 # are optional numerical parameters (default 1 and 5000, which means once
472 # and 5 seconds). Please notes that if any of the values defined here is
473 # more than what is defined in krb5.conf, it will be ignored.
474 #
475 # Whenever a KDC is detected as available, it is removed from the blacklist.
476 # The blacklist is reset when krb5.conf is reloaded. You can add
477 # refreshKrb5Config=true to a JAAS configuration file so that krb5.conf is
478 # reloaded whenever a JAAS authentication is attempted.
479 #
480 # Example,
481 # krb5.kdc.bad.policy = tryLast

485 # Algorithm restrictions for certification path (CertPath) processing
486 #
487 # In some environments, certain algorithms or key lengths may be undesirable
488 # for certification path building and validation. For example, "MD2" is
489 # generally no longer considered to be a secure hash algorithm. This section
490 # describes the mechanism for disabling algorithms based on algorithm name
491 # and/or key length. This includes algorithms used in certificates, as well
492 # as revocation information such as CRLs and signed OCSP Responses.
493 #
494 # The syntax of the disabled algorithm string is described as this Java
495 # BNF-style:
496 # DisabledAlgorithms:
497 # " DisabledAlgorithm { , DisabledAlgorithm } "
498 #
499 # DisabledAlgorithm:
500 # AlgorithmName [Constraint]
501 #
502 # AlgorithmName:
503 # (see below)

508 # KeySizeConstraint:

519 #
520 # DecimalDigit: one of
521 # 1 2 3 4 5 6 7 8 9 0
522 #
523 # The "AlgorithmName" is the standard algorithm name of the disabled
524 # algorithm. See "Java Cryptography Architecture Standard Algorithm Name
525 # Documentation" for information about Standard Algorithm Names. Matching
526 # is performed using a case-insensitive sub-element matching rule. (For
527 # example, in "SHA1withECDSA" the sub-elements are "SHA1" for hashing and
528 # "ECDSA" for signatures.) If the assertion "AlgorithmName" is a
529 # sub-element of the certificate algorithm name, the algorithm will be
530 # rejected during certification path building and validation. For example,
531 # the assertion algorithm name "DSA" will disable all certificate algorithms
532 # that rely on DSA, such as NONEwithDSA, SHA1withDSA. However, the assertion
533 # will not disable algorithms related to "ECDSA".
534 #
535 # A "Constraint" provides further guidance for the algorithm being specified.
536 # The "KeySizeConstraint" requires a key of a valid size range if the
537 # "AlgorithmName" is of a key algorithm. The "DecimalInteger" indicates the
538 # key size specified in number of bits. For example, "RSA keySize <= 1024"
539 # indicates that any RSA key with key size less than or equal to 1024 bits
540 # should be disabled, and "RSA keySize < 1024, RSA keySize > 2048" indicates
541 # that any RSA key with key size less than 1024 or greater than 2048 should
542 # be disabled. Note that the "KeySizeConstraint" only makes sense to key

555 # Algorithm restrictions for Secure Socket Layer/Transport Layer Security
556 # (SSL/TLS/DTLS) processing
557 #
558 # In some environments, certain algorithms or key lengths may be undesirable
559 # when using SSL/TLS/DTLS. This section describes the mechanism for disabling
560 # algorithms during SSL/TLS/DTLS security parameters negotiation, including
561 # protocol version negotiation, cipher suites selection, peer authentication
562 # and key exchange mechanisms.
563 #
564 # Disabled algorithms will not be negotiated for SSL/TLS connections, even
565 # if they are enabled explicitly in an application.
566 #
567 # For PKI-based peer authentication and key exchange mechanisms, this list
568 # of disabled algorithms will also be checked during certification path
569 # building and validation, including algorithms used in certificates, as
570 # well as revocation information such as CRLs and signed OCSP Responses.
571 # This is in addition to the jdk.certpath.disabledAlgorithms property above.
572 #
573 # See the specification of "jdk.certpath.disabledAlgorithms" for the
574 # syntax of the disabled algorithm string.
575 #
576 # Note: This property is currently used by Oracle's JSSE implementation.
577 # It is not guaranteed to be examined and used by other implementations.
578 #
579 # Example:
580 # jdk.tls.disabledAlgorithms=MD5, SSLv3, DSA, RSA keySize < 2048
581 jdk.tls.disabledAlgorithms=SSLv3, RC4, MD5withRSA, DH keySize < 1024

583 # Legacy algorithms for Secure Socket Layer/Transport Layer Security (SSL/TLS)
584 # processing in JSSE implementation.
585 #
586 # In some environments, a certain algorithm may be undesirable but it
587 # cannot be disabled because of its use in legacy applications. Legacy
588 # algorithms may still be supported, but applications should not use them
589 # as the security strength of legacy algorithms are usually not strong enough
590 # in practice.
591 #
592 # During SSL/TLS security parameters negotiation, legacy algorithms will
593 # not be negotiated unless there are no other candidates.
594 #
595 # The syntax of the disabled algorithm string is described as this Java
596 # BNF-style:
597 # LegacyAlgorithms:
598 # " LegacyAlgorithm { , LegacyAlgorithm } "
599 #
600 # LegacyAlgorithm:
601 # AlgorithmName (standard JSSE algorithm name)
602 #
603 # See the specification of security property "jdk.certpath.disabledAlgorithms"
604 # for the syntax and description of the "AlgorithmName" notation.
605 #
606 # Per SSL/TLS specifications, cipher suites have the form:
607 # SSL_KeyExchangeAlg_WITH_CipherAlg_MacAlg
608 # or
609 # TLS_KeyExchangeAlg_WITH_CipherAlg_MacAlg
610 #
611 # For example, the cipher suite TLS_RSA_WITH_AES_128_CBC_SHA uses RSA as the
612 # key exchange algorithm, AES_128_CBC (128 bits AES cipher algorithm in CBC
613 # mode) as the cipher (encryption) algorithm, and SHA-1 as the message digest
614 # algorithm for HMAC.
615 #
616 # The LegacyAlgorithm can be one of the following standard algorithm names:
617 # 1. JSSE cipher suite name, e.g., TLS_RSA_WITH_AES_128_CBC_SHA
618 # 2. JSSE key exchange algorithm name, e.g., RSA
619 # 3. JSSE cipher (encryption) algorithm name, e.g., AES_128_CBC
620 # 4. JSSE message digest algorithm name, e.g., SHA
621 #
622 # See SSL/TLS specifications and "Java Cryptography Architecture Standard
623 # Algorithm Name Documentation" for information about the algorithm names.
624 #
625 # Note: This property is currently used by Oracle's JSSE implementation.
626 # It is not guaranteed to be examined and used by other implementations.
627 # There is no guarantee the property will continue to exist or be of the
628 # same syntax in future releases.
629 #
630 # Example:
631 # jdk.tls.legacyAlgorithms=DH_anon, DES_CBC, SSL_RSA_WITH_RC4_128_MD5
632 #
633 jdk.tls.legacyAlgorithms= \
634 K_NULL, C_NULL, M_NULL, \
635 DHE_DSS_EXPORT, DHE_RSA_EXPORT, DH_anon_EXPORT, DH_DSS_EXPORT, \

640 # The pre-defined default finite field Diffie-Hellman ephemeral (DHE)
641 # parameters for Transport Layer Security (SSL/TLS/DTLS) processing.
642 #
643 # In traditional SSL/TLS/DTLS connections where finite field DHE parameters
644 # negotiation mechanism is not used, the server offers the client group
645 # parameters, base generator g and prime modulus p, for DHE key exchange.
646 # It is recommended to use dynamic group parameters. This property defines
647 # a mechanism that allows you to specify custom group parameters.
648 #
649 # The syntax of this property string is described as this Java BNF-style:
650 # DefaultDHEParameters:
651 # DefinedDHEParameters { , DefinedDHEParameters }
652 #
653 # DefinedDHEParameters:
654 # "{" DHEPrimeModulus , DHEBaseGenerator "}"

656 # DHEPrimeModulus:
657 # HexadecimalDigits
658 #
659 # DHEBaseGenerator:
660 # HexadecimalDigits
661 #
662 # HexadecimalDigits:
663 # HexadecimalDigit { HexadecimalDigit }
664 #
665 # HexadecimalDigit: one of
666 # 0 1 2 3 4 5 6 7 8 9 A B C D E F a b c d e f
667 #
668 # Whitespace characters are ignored.
669 #
670 # The "DefinedDHEParameters" defines the custom group parameters, prime
671 # modulus p and base generator g, for a particular size of prime modulus p.
672 # The "DHEPrimeModulus" defines the hexadecimal prime modulus p, and the
673 # "DHEBaseGenerator" defines the hexadecimal base generator g of a group
674 # parameter. It is recommended to use safe primes for the custom group
675 # parameters.
676 #
677 # If this property is not defined or the value is empty, the underlying JSSE
678 # provider's default group parameter is used for each connection.
679 #
680 # If the property value does not follow the grammar, or a particular group
681 # parameter is not valid, the connection will fall back and use the
682 # underlying JSSE provider's default group parameter.
