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.
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
38 # security.provider.<n>=<className>
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
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.
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:
57 # security.provider.1=sun.security.provider.Sun
59 # (The number 1 is used for the default provider.)
61 # Note: Providers can be dynamically registered instead by calls to
62 # either the addProvider or insertProviderAt method in the Security
66 # List of providers and their preference orders (see above):
68 security.provider.1=sun.security.provider.Sun

84 # (Other SecureRandom implementations might also use this property.)
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.
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.
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:
99 # the traditional system/thread activity algorithm will be used.
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.
106 # The entropy gathering device can also be specified with the System
107 # property "java.security.egd". For example:
109 # % java -Djava.security.egd=file:/dev/random MainClass
111 # Specifying this System property will override the
112 # "securerandom.source" Security property.

448 # Algorithm restrictions for certification path (CertPath) processing
450 # In some environments, certain algorithms or key lengths may be undesirable
451 # for certification path building and validation. For example, "MD2" is
452 # generally no longer considered to be a secure hash algorithm. This section
453 # describes the mechanism for disabling algorithms based on algorithm name
454 # and/or key length. This includes algorithms used in certificates, as well
455 # as revocation information such as CRLs and signed OCSP Responses.
456 # The syntax of the disabled algorithm string is described as follows:
457 # DisabledAlgorithms:
458 # " DisabledAlgorithm { , DisabledAlgorithm } "
461 # AlgorithmName [Constraint] { '&' Constraint }
467 # KeySizeConstraint | CAConstraint | DenyAfterConstraint |
471 # keySize Operator KeyLength
474 # <= | < | == | != | >= | >
477 # Integer value of the algorithm's key length in bits
482 # DenyAfterConstraint:
483 # denyAfter YYYY-MM-DD
486 # usage [TLSServer] [TLSClient] [SignedJAR]
488 # The "AlgorithmName" is the standard algorithm name of the disabled
489 # algorithm. See "Java Cryptography Architecture Standard Algorithm Name
490 # Documentation" for information about Standard Algorithm Names. Matching
491 # is performed using a case-insensitive sub-element matching rule. (For
492 # example, in "SHA1withECDSA" the sub-elements are "SHA1" for hashing and
493 # "ECDSA" for signatures.) If the assertion "AlgorithmName" is a
494 # sub-element of the certificate algorithm name, the algorithm will be
495 # rejected during certification path building and validation. For example,
496 # the assertion algorithm name "DSA" will disable all certificate algorithms
497 # that rely on DSA, such as NONEwithDSA, SHA1withDSA. However, the assertion
498 # will not disable algorithms related to "ECDSA".
500 # A "Constraint" defines restrictions on the keys and/or certificates for
501 # a specified AlgorithmName:
504 # keySize Operator KeyLength
505 # The constraint requires a key of a valid size range if the
506 # "AlgorithmName" is of a key algorithm. The "KeyLength" indicates
507 # the key size specified in number of bits. For example,
508 # "RSA keySize <= 1024" indicates that any RSA key with key size less
509 # than or equal to 1024 bits should be disabled, and
510 # "RSA keySize < 1024, RSA keySize > 2048" indicates that any RSA key
511 # with key size less than 1024 or greater than 2048 should be disabled.
512 # This constraint is only used on algorithms that have a key size.
516 # This constraint prohibits the specified algorithm only if the
517 # algorithm is used in a certificate chain that terminates at a marked
518 # trust anchor in the lib/security/cacerts keystore. If the jdkCA
519 # constraint is not set, then all chains using the specified algorithm
520 # are restricted. jdkCA may only be used once in a DisabledAlgorithm
522 # Example: To apply this constraint to SHA-1 certificates, include
523 # the following: "SHA1 jdkCA"
525 # DenyAfterConstraint:
526 # denyAfter YYYY-MM-DD
527 # This constraint prohibits a certificate with the specified algorithm
528 # from being used after the date regardless of the certificate's
529 # validity. JAR files that are signed and timestamped before the
530 # constraint date with certificates containing the disabled algorithm
531 # will not be restricted. The date is processed in the UTC timezone.
532 # This constraint can only be used once in a DisabledAlgorithm
534 # Example: To deny usage of RSA 2048 bit certificates after Feb 3 2020,
535 # use the following: "RSA keySize == 2048 & denyAfter 2020-02-03"
538 # usage [TLSServer] [TLSClient] [SignedJAR]
539 # This constraint prohibits the specified algorithm for
540 # a specified usage. This should be used when disabling an algorithm
541 # for all usages is not practical. 'TLSServer' restricts the algorithm
542 # in TLS server certificate chains when server authentication is
543 # performed. 'TLSClient' restricts the algorithm in TLS client
544 # certificate chains when client authentication is performed.
545 # 'SignedJAR' constrains use of certificates in signed jar files.
546 # The usage type follows the keyword and more than one usage type can
547 # be specified with a whitespace delimiter.
548 # Example: "SHA1 usage TLSServer TLSClient"
550 # When an algorithm must satisfy more than one constraint, it must be
551 # delimited by an ampersand '&'. For example, to restrict certificates in a
552 # chain that terminate at a distribution provided trust anchor and contain
553 # RSA keys that are less than or equal to 1024 bits, add the following
554 # constraint: "RSA keySize <= 1024 & jdkCA".
556 # All DisabledAlgorithms expressions are processed in the order defined in the
557 # property. This requires lower keysize constraints to be specified
558 # before larger keysize constraints of the same algorithm. For example:
559 # "RSA keySize < 1024 & jdkCA, RSA keySize < 2048".
561 # Note: The algorithm restrictions do not apply to trust anchors or
562 # self-signed certificates.

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

679 # key exchange algorithm, AES_128_CBC (128 bits AES cipher algorithm in CBC
680 # mode) as the cipher (encryption) algorithm, and SHA-1 as the message digest
681 # algorithm for HMAC.
683 # The LegacyAlgorithm can be one of the following standard algorithm names:
684 # 1. JSSE cipher suite name, e.g., TLS_RSA_WITH_AES_128_CBC_SHA
685 # 2. JSSE key exchange algorithm name, e.g., RSA
686 # 3. JSSE cipher (encryption) algorithm name, e.g., AES_128_CBC
687 # 4. JSSE message digest algorithm name, e.g., SHA
689 # See SSL/TLS specifications and "Java Cryptography Architecture Standard
690 # Algorithm Name Documentation" for information about the algorithm names.

763 # Cryptographic Jurisdiction Policy defaults
765 # Import and export control rules on cryptographic software vary from
766 # country to country. By default, the JDK provides two different sets of
767 # cryptographic policy files:
769 # unlimited: These policy files contain no restrictions on cryptographic
770 # strengths or algorithms.
772 # limited: These policy files contain more restricted cryptographic
773 # strengths, and are still available if your country or
774 # usage requires the traditional restrictive policy.
776 # The JDK JCE framework uses the unlimited policy files by default.
777 # However the user may explicitly choose a set either by defining the
778 # "crypto.policy" Security property or by installing valid JCE policy
779 # jar files into the traditional JDK installation location. To better
780 # support older JDK Update releases, the "crypto.policy" property is not
781 # defined by default. See below for more information.
783 # The following logic determines which policy files are used:
785 # <java-home> refers to the directory where the JRE was
786 # installed and may be determined using the "java.home"
789 # 1. If the Security property "crypto.policy" has been defined,
790 # then the following mechanism is used:
792 # The policy files are stored as jar files in subdirectories of
793 # <java-home>/lib/security/policy. Each directory contains a complete
794 # set of policy files.
796 # The "crypto.policy" Security property controls the directory
797 # selection, and thus the effective cryptographic policy.
799 # The default set of directories is:
801 # limited | unlimited
803 # 2. If the "crypto.policy" property is not set and the traditional
804 # US_export_policy.jar and local_policy.jar files
805 # (e.g. limited/unlimited) are found in the legacy
806 # <java-home>/lib/security directory, then the rules embedded within
807 # those jar files will be used. This helps preserve compatibility
808 # for users upgrading from an older installation.
810 # 3. If the jar files are not present in the legacy location
811 # and the "crypto.policy" Security property is not defined,
812 # then the JDK will use the unlimited settings (equivalent to
813 # crypto.policy=unlimited)

818 # YOU ARE ADVISED TO CONSULT YOUR EXPORT/IMPORT CONTROL COUNSEL OR ATTORNEY
819 # TO DETERMINE THE EXACT REQUIREMENTS.

880 # Serialization process-wide filter
882 # A filter, if configured, is used by java.io.ObjectInputStream during
883 # deserialization to check the contents of the stream.
884 # A filter is configured as a sequence of patterns, each pattern is either
885 # matched against the name of a class in the stream or defines a limit.
886 # Patterns are separated by ";" (semicolon).
887 # Whitespace is significant and is considered part of the pattern.
889 # If the system property jdk.serialFilter is also specified, it supersedes
890 # the security property value defined here.
892 # If a pattern includes a "=", it sets a limit.
893 # If a limit appears more than once the last value is used.
894 # Limits are checked before classes regardless of the order in the sequence of patterns.
895 # If any of the limits are exceeded, the filter status is REJECTED.
897 # maxdepth=value - the maximum depth of a graph
898 # maxrefs=value - the maximum number of internal references
899 # maxbytes=value - the maximum number of bytes in the input stream
900 # maxarray=value - the maximum array length allowed
902 # Other patterns, from left to right, match the class or package name as
903 # returned from Class.getName.
904 # If the class is an array type, the class or package to be matched is the element type.
905 # Arrays of any number of dimensions are treated the same as the element type.
906 # For example, a pattern of "!example.Foo", rejects creation of any instance or
907 # array of example.Foo.
909 # If the pattern starts with "!", the status is REJECTED if the remaining pattern
910 # is matched; otherwise the status is ALLOWED if the pattern matches.
911 # If the pattern ends with ".**" it matches any class in the package and all subpackages.
912 # If the pattern ends with ".*" it matches any class in the package.
913 # If the pattern ends with "*", it matches any class with the pattern as a prefix.
914 # If the pattern is equal to the class name, it matches.
915 # Otherwise, the status is UNDECIDED.

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

930 # component type, including subarrays and arrays of primitives, are allowed.
932 # Array construction of any component type, including subarrays and arrays of
933 # primitives, are allowed unless the length is greater than the maxarray limit.
934 # The filter is applied to each array element.
