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): 67 # 68 security.provider.1=sun.security.provider.Sun 69 security.provider.2=sun.security.rsa.SunRsaSign 70 security.provider.3=sun.security.ec.SunEC 71 security.provider.4=com.sun.net.ssl.internal.ssl.Provider 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 76 security.provider.9=sun.security.smartcardio.SunPCSC 77 78 # 79 # Sun Provider SecureRandom seed source. 80 # 81 # Select the primary source of seed data for the "SHA1PRNG" and 82 # "NativePRNG" SecureRandom implementations in the "Sun" provider. 83 # (Other SecureRandom implementations might also use this property.) 84 # 85 # On Unix-like systems (for example, Solaris/Linux/MacOS), the 86 # "NativePRNG" and "SHA1PRNG" implementations obtains seed data from 87 # special device files such as file:/dev/random. 88 # 89 # On Windows systems, specifying the URLs "file:/dev/random" or 90 # "file:/dev/urandom" will enable the native Microsoft CryptoAPI seeding 91 # mechanism for SHA1PRNG. 92 # 93 # By default, an attempt is made to use the entropy gathering device 94 # specified by the "securerandom.source" Security property.

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". 530 # 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 537 # self-signed certificates. 538 # 539 # Note: This property is currently used by Oracle's PKIX implementation.

By default, the JDK provides two different sets of 742 # cryptographic policy files: 743 # 744 # unlimited: These policy files contain no restrictions on cryptographic 745 # strengths or algorithms. 746 # 747 # limited: These policy files contain more restricted cryptographic 748 # strengths, and are still available if your country or 749 # usage requires the traditional restrictive policy. 750 # 751 # The JDK JCE framework uses the unlimited policy files by default. 752 # However the user may explicitly choose a set either by defining the 753 # "crypto.policy" Security property or by installing valid JCE policy 754 # jar files into the traditional JDK installation location. To better 755 # support older JDK Update releases, the "crypto.policy" property is not 756 # defined by default. See below for more information. 757 # 758 # The following logic determines which policy files are used: 759 # 760 # <java-home> refers to the directory where the JRE was 761 # installed and may be determined using the "java.home" 762 # System property. 763 # 764 # 1. If the Security property "crypto.policy" has been defined, 765 # then the following mechanism is used: 766 # 767 # The policy files are stored as jar files in subdirectories of 768 # <java-home>/lib/security/policy. Each directory contains a complete 769 # set of policy files. 770 # 771 # The "crypto.policy" Security property controls the directory 772 # selection, and thus the effective cryptographic policy. 773 # 774 # The default set of directories is: 775 # 776 # limited | unlimited 777 # 778 # 2. If the "crypto.policy" property is not set and the traditional 779 # US_export_policy.jar and local_policy.jar files 780 # (e.g. limited/unlimited) are found in the legacy 781 # <java-home>/lib/security directory, then the rules embedded within 782 # those jar files will be used. This helps preserve compatibility 783 # for users upgrading from an older installation. 784 # 785 # 3. If the jar files are not present in the legacy location 786 # and the "crypto.policy" Security property is not defined, 787 # then the JDK will use the unlimited settings (equivalent to 788 # crypto.policy=unlimited) 789 # 790 # Please see the JCA documentation for additional information on these 791 # files and formats. 792 # 793 # YOU ARE ADVISED TO CONSULT YOUR EXPORT/IMPORT CONTROL COUNSEL OR ATTORNEY 794 # TO DETERMINE THE EXACT REQUIREMENTS. 795 # 796 # Please note that the JCE for Java SE, including the JCE framework, 797 # cryptographic policy files, and standard JCE providers provided with 798 # the Java SE, have been reviewed and approved for export as mass market 799 # encryption item by the US Bureau of Industry and Security. 800 # 801 # Note: This property is currently used by the JDK Reference implementation. 802 # It is not guaranteed to be examined and used by other implementations. 803 # 804 #crypto.policy=unlimited 805 806 # 807 # The policy for the XML Signature secure validation mode.
