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.

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

328 # Enable OCSP
329 #
330 # By default, OCSP is not used for certificate revocation checking.
331 # This property enables the use of OCSP when set to the value "true".

335 # Example,
336 # ocsp.enable=true
337
338 #
339 # Location of the OCSP responder
340 #
341 # By default, the location of the OCSP responder is determined implicitly
342 # from the certificate being validated. This property explicitly specifies
343 # the location of the OCSP responder. The property is used when the
344 # Authority Information Access extension (defined in RFC 3280) is absent
345 # from the certificate or when it requires overriding.
346 #
347 # Example,
348 # ocsp.responderURL=http://ocsp.example.net:80
349
350 #
351 # Subject name of the OCSP responder's certificate
352 #
353 # By default, the certificate of the OCSP responder is that of the issuer
354 # of the certificate being validated. This property identifies the certificate
355 # of the OCSP responder when the default does not apply. Its value is a string
356 # distinguished name (defined in RFC 2253) which identifies a certificate in
357 # the set of certificates supplied during cert path validation. In cases where
358 # the subject name alone is not sufficient to uniquely identify the certificate
359 # then both the "ocsp.responderCertIssuerName" and
360 # "ocsp.responderCertSerialNumber" properties must be used instead. When this
361 # property is set then those two properties are ignored.
362 #
363 # Example,
364 # ocsp.responderCertSubjectName="CN=OCSP Responder, O=XYZ Corp"
365
366 #
367 # Issuer name of the OCSP responder's certificate
368 #
369 # By default, the certificate of the OCSP responder is that of the issuer
370 # of the certificate being validated. This property identifies the certificate
371 # of the OCSP responder when the default does not apply. Its value is a string
372 # distinguished name (defined in RFC 2253) which identifies a certificate in
373 # the set of certificates supplied during cert path validation. When this
374 # property is set then the "ocsp.responderCertSerialNumber" property must also
375 # be set. When the "ocsp.responderCertSubjectName" property is set then this
376 # property is ignored.
377 #
378 # Example,
379 # ocsp.responderCertIssuerName="CN=Enterprise CA, O=XYZ Corp"
380
381 #
382 # Serial number of the OCSP responder's certificate
383 #
384 # By default, the certificate of the OCSP responder is that of the issuer
385 # of the certificate being validated. This property identifies the certificate
386 # of the OCSP responder when the default does not apply. Its value is a string
387 # of hexadecimal digits (colon or space separators may be present) which
388 # identifies a certificate in the set of certificates supplied during cert path
389 # validation. When this property is set then the "ocsp.responderCertIssuerName"
390 # property must also be set. When the "ocsp.responderCertSubjectName" property
391 # is set then this property is ignored.

397 # Policy for failed Kerberos KDC lookups:
398 #
399 # When a KDC is unavailable (network error, service failure, etc), it is

401 # value (case-insensitive) for this policy can be:
402 #
403 # tryLast
404 # KDCs in the blacklist are always tried after those not on the list.
405 #
406 # tryLess[:max_retries,timeout]
407 # KDCs in the blacklist are still tried by their order in the configuration,
408 # but with smaller max_retries and timeout values. max_retries and timeout
409 # are optional numerical parameters (default 1 and 5000, which means once
410 # and 5 seconds). Please notes that if any of the values defined here is
411 # more than what is defined in krb5.conf, it will be ignored.
412 #
413 # Whenever a KDC is detected as available, it is removed from the blacklist.
414 # The blacklist is reset when krb5.conf is reloaded. You can add
415 # refreshKrb5Config=true to a JAAS configuration file so that krb5.conf is
416 # reloaded whenever a JAAS authentication is attempted.
417 #
418 # Example,

423 # Algorithm restrictions for certification path (CertPath) processing
424 #
425 # In some environments, certain algorithms or key lengths may be undesirable
426 # for certification path building and validation. For example, "MD2" is
427 # generally no longer considered to be a secure hash algorithm. This section
428 # describes the mechanism for disabling algorithms based on algorithm name
429 # and/or key length. This includes algorithms used in certificates, as well
430 # as revocation information such as CRLs and signed OCSP Responses.
431 # The syntax of the disabled algorithm string is described as follows:
432 # DisabledAlgorithms:
433 # " DisabledAlgorithm { , DisabledAlgorithm } "
434 #
435 # DisabledAlgorithm:
436 # AlgorithmName [Constraint] { '&' Constraint }
437 #
438 # AlgorithmName:
439 # (see below)
440 #
441 # Constraint:
442 # KeySizeConstraint | CAConstraint | DenyAfterConstraint |
443 # UsageConstraint
444 #
445 # KeySizeConstraint:
446 # keySize Operator KeyLength
447 #
448 # Operator:
449 # <= | < | == | != | >= | >
450 #
451 # KeyLength:
452 # Integer value of the algorithm's key length in bits
453 #
454 # CAConstraint:
455 # jdkCA
456 #
457 # DenyAfterConstraint:
458 # denyAfter YYYY-MM-DD
459 #
460 # UsageConstraint:
461 # usage [TLSServer] [TLSClient] [SignedJAR]
462 #
463 # The "AlgorithmName" is the standard algorithm name of the disabled
464 # algorithm. See "Java Cryptography Architecture Standard Algorithm Name
465 # Documentation" for information about Standard Algorithm Names. Matching
466 # is performed using a case-insensitive sub-element matching rule. (For
467 # example, in "SHA1withECDSA" the sub-elements are "SHA1" for hashing and
468 # "ECDSA" for signatures.) If the assertion "AlgorithmName" is a
469 # sub-element of the certificate algorithm name, the algorithm will be
470 # rejected during certification path building and validation. For example,
471 # the assertion algorithm name "DSA" will disable all certificate algorithms
472 # that rely on DSA, such as NONEwithDSA, SHA1withDSA. However, the assertion
473 # will not disable algorithms related to "ECDSA".
474 #
475 # A "Constraint" defines restrictions on the keys and/or certificates for
476 # a specified AlgorithmName:
477 #
478 # KeySizeConstraint:
479 # keySize Operator KeyLength
480 # The constraint requires a key of a valid size range if the
481 # "AlgorithmName" is of a key algorithm. The "KeyLength" indicates
482 # the key size specified in number of bits. For example,
483 # "RSA keySize <= 1024" indicates that any RSA key with key size less
484 # than or equal to 1024 bits should be disabled, and
485 # "RSA keySize < 1024, RSA keySize > 2048" indicates that any RSA key
486 # with key size less than 1024 or greater than 2048 should be disabled.
487 # This constraint is only used on algorithms that have a key size.
488 #
489 # CAConstraint:
490 # jdkCA
491 # This constraint prohibits the specified algorithm only if the
492 # algorithm is used in a certificate chain that terminates at a marked
493 # trust anchor in the lib/security/cacerts keystore. If the jdkCA
494 # constraint is not set, then all chains using the specified algorithm
495 # are restricted. jdkCA may only be used once in a DisabledAlgorithm
496 # expression.
497 # Example: To apply this constraint to SHA-1 certificates, include
498 # the following: "SHA1 jdkCA"
499 #
500 # DenyAfterConstraint:
501 # denyAfter YYYY-MM-DD
502 # This constraint prohibits a certificate with the specified algorithm
503 # from being used after the date regardless of the certificate's
504 # validity. JAR files that are signed and timestamped before the
505 # constraint date with certificates containing the disabled algorithm
506 # will not be restricted. The date is processed in the UTC timezone.
507 # This constraint can only be used once in a DisabledAlgorithm
508 # expression.
509 # Example: To deny usage of RSA 2048 bit certificates after Feb 3 2020,
510 # use the following: "RSA keySize == 2048 & denyAfter 2020-02-03"
511 #
512 # UsageConstraint:
513 # usage [TLSServer] [TLSClient] [SignedJAR]
514 # This constraint prohibits the specified algorithm for
515 # a specified usage. This should be used when disabling an algorithm
516 # for all usages is not practical. 'TLSServer' restricts the algorithm
517 # in TLS server certificate chains when server authentication is
518 # performed. 'TLSClient' restricts the algorithm in TLS client
519 # certificate chains when client authentication is performed.
520 # 'SignedJAR' constrains use of certificates in signed jar files.
521 # The usage type follows the keyword and more than one usage type can
522 # be specified with a whitespace delimiter.
523 # Example: "SHA1 usage TLSServer TLSClient"
524 #
525 # When an algorithm must satisfy more than one constraint, it must be
526 # delimited by an ampersand '&'. For example, to restrict certificates in a
527 # chain that terminate at a distribution provided trust anchor and contain
528 # RSA keys that are less than or equal to 1024 bits, add the following
529 # constraint: "RSA keySize <= 1024 & jdkCA".

531 # All DisabledAlgorithms expressions are processed in the order defined in the
532 # property. This requires lower keysize constraints to be specified
533 # before larger keysize constraints of the same algorithm. For example:
534 # "RSA keySize < 1024 & jdkCA, RSA keySize < 2048".
535 #
536 # Note: The algorithm restrictions do not apply to trust anchors or

555 # mechanism for disabling algorithms based on algorithm name and/or key length.
556 # JARs signed with any of the disabled algorithms or key sizes will be treated
557 # as unsigned.
558 #
559 # The syntax of the disabled algorithm string is described as follows:

593 # Algorithm restrictions for Secure Socket Layer/Transport Layer Security
594 # (SSL/TLS) processing
595 #
596 # In some environments, certain algorithms or key lengths may be undesirable
597 # when using SSL/TLS. This section describes the mechanism for disabling
598 # algorithms during SSL/TLS security parameters negotiation, including
599 # protocol version negotiation, cipher suites selection, peer authentication
600 # and key exchange mechanisms.
601 #
602 # Disabled algorithms will not be negotiated for SSL/TLS connections, even
603 # if they are enabled explicitly in an application.
604 #
605 # For PKI-based peer authentication and key exchange mechanisms, this list
606 # of disabled algorithms will also be checked during certification path
607 # building and validation, including algorithms used in certificates, as
608 # well as revocation information such as CRLs and signed OCSP Responses.
609 # This is in addition to the jdk.certpath.disabledAlgorithms property above.
610 #
611 # See the specification of "jdk.certpath.disabledAlgorithms" for the
612 # syntax of the disabled algorithm string.
613 #

615 # self-signed certificates.
616 #
617 # Note: This property is currently used by the JDK Reference implementation.
618 # It is not guaranteed to be examined and used by other implementations.
619 #
620 # Example:
621 # jdk.tls.disabledAlgorithms=MD5, SSLv3, DSA, RSA keySize < 2048

625 # Legacy algorithms for Secure Socket Layer/Transport Layer Security (SSL/TLS)
626 # processing in JSSE implementation.
627 #
628 # In some environments, a certain algorithm may be undesirable but it
629 # cannot be disabled because of its use in legacy applications. Legacy
630 # algorithms may still be supported, but applications should not use them
631 # as the security strength of legacy algorithms are usually not strong enough
632 # in practice.
633 #
634 # During SSL/TLS security parameters negotiation, legacy algorithms will
635 # not be negotiated unless there are no other candidates.
636 #
637 # The syntax of the legacy algorithms string is described as this Java
638 # BNF-style:
639 # LegacyAlgorithms:
640 # " LegacyAlgorithm { , LegacyAlgorithm } "
641 #
642 # LegacyAlgorithm:
643 # AlgorithmName (standard JSSE algorithm name)
644 #
645 # See the specification of security property "jdk.certpath.disabledAlgorithms"
646 # for the syntax and description of the "AlgorithmName" notation.
647 #
648 # Per SSL/TLS specifications, cipher suites have the form:
649 # SSL_KeyExchangeAlg_WITH_CipherAlg_MacAlg
650 # or
651 # TLS_KeyExchangeAlg_WITH_CipherAlg_MacAlg
652 #
653 # For example, the cipher suite TLS_RSA_WITH_AES_128_CBC_SHA uses RSA as the
654 # key exchange algorithm, AES_128_CBC (128 bits AES cipher algorithm in CBC
655 # mode) as the cipher (encryption) algorithm, and SHA-1 as the message digest
656 # algorithm for HMAC.
657 #
658 # The LegacyAlgorithm can be one of the following standard algorithm names:
659 # 1. JSSE cipher suite name, e.g., TLS_RSA_WITH_AES_128_CBC_SHA
660 # 2. JSSE key exchange algorithm name, e.g., RSA
661 # 3. JSSE cipher (encryption) algorithm name, e.g., AES_128_CBC
662 # 4. JSSE message digest algorithm name, e.g., SHA
663 #
664 # See SSL/TLS specifications and "Java Cryptography Architecture Standard
665 # Algorithm Name Documentation" for information about the algorithm names.

689 # It is recommended to use dynamic group parameters. This property defines

711 # Whitespace characters are ignored.
712 #
713 # The "DefinedDHEParameters" defines the custom group parameters, prime
714 # modulus p and base generator g, for a particular size of prime modulus p.
715 # The "DHEPrimeModulus" defines the hexadecimal prime modulus p, and the
716 # "DHEBaseGenerator" defines the hexadecimal base generator g of a group
717 # parameter. It is recommended to use safe primes for the custom group
718 # parameters.
719 #
720 # If this property is not defined or the value is empty, the underlying JSSE
721 # provider's default group parameter is used for each connection.
722 #

788 # Serialization process-wide filter
789 #
790 # A filter, if configured, is used by java.io.ObjectInputStream during
791 # deserialization to check the contents of the stream.
792 # A filter is configured as a sequence of patterns, each pattern is either
793 # matched against the name of a class in the stream or defines a limit.
794 # Patterns are separated by ";" (semicolon).
795 # Whitespace is significant and is considered part of the pattern.
796 #
797 # If a pattern includes a "=", it sets a limit.
798 # If a limit appears more than once the last value is used.
799 # Limits are checked before classes regardless of the order in the sequence of patterns.
800 # If any of the limits are exceeded, the filter status is REJECTED.
801 #
802 # maxdepth=value - the maximum depth of a graph
803 # maxrefs=value - the maximum number of internal references
804 # maxbytes=value - the maximum number of bytes in the input stream
805 # maxarray=value - the maximum array length allowed
806 #
807 # Other patterns, from left to right, match the class or package name as
808 # returned from Class.getName.
809 # If the class is an array type, the class or package to be matched is the element type.
810 # Arrays of any number of dimensions are treated the same as the element type.
811 # For example, a pattern of "!example.Foo", rejects creation of any instance or
812 # array of example.Foo.
813 #
814 # If the pattern starts with "!", the status is REJECTED if the remaining pattern
815 # is matched; otherwise the status is ALLOWED if the pattern matches.
816 # If the pattern ends with ".**" it matches any class in the package and all subpackages.
817 # If the pattern ends with ".*" it matches any class in the package.
818 # If the pattern ends with "*", it matches any class with the pattern as a prefix.
