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

By default, the JDK provides two different sets of 748 # cryptographic policy files: 749 # 750 # unlimited: These policy files contain no restrictions on cryptographic 751 # strengths or algorithms. 752 # 753 # limited: These policy files contain more restricted cryptographic 754 # strengths, and are still available if your country or 755 # usage requires the traditional restrictive policy. 756 # 757 # The JDK JCE framework uses the unlimited policy files by default. 758 # However the user may explicitly choose a set either by defining the 759 # "crypto.policy" Security property or by installing valid JCE policy 760 # jar files into the traditional JDK installation location. To better 761 # support older JDK Update releases, the "crypto.policy" property is not 762 # defined by default. See below for more information. 763 # 764 # The following logic determines which policy files are used: 765 # 766 # <java-home> refers to the directory where the JRE was 767 # installed and may be determined using the "java.home" 768 # System property. 769 # 770 # 1. If the Security property "crypto.policy" has been defined, 771 # then the following mechanism is used: 772 # 773 # The policy files are stored as jar files in subdirectories of 774 # <java-home>/lib/security/policy. Each directory contains a complete 775 # set of policy files. 776 # 777 # The "crypto.policy" Security property controls the directory 778 # selection, and thus the effective cryptographic policy. 779 # 780 # The default set of directories is: 781 # 782 # limited | unlimited 783 # 784 # 2. If the "crypto.policy" property is not set and the traditional 785 # US_export_policy.jar and local_policy.jar files 786 # (e.g. limited/unlimited) are found in the legacy 787 # <java-home>/lib/security directory, then the rules embedded within 788 # those jar files will be used. This helps preserve compatibility 789 # for users upgrading from an older installation. 790 # 791 # 3. If the jar files are not present in the legacy location 792 # and the "crypto.policy" Security property is not defined, 793 # then the JDK will use the unlimited settings (equivalent to 794 # crypto.policy=unlimited) 795 # 796 # Please see the JCA documentation for additional information on these 797 # files and formats. 798 # 799 # YOU ARE ADVISED TO CONSULT YOUR EXPORT/IMPORT CONTROL COUNSEL OR ATTORNEY 800 # TO DETERMINE THE EXACT REQUIREMENTS. 801 # 802 # Please note that the JCE for Java SE, including the JCE framework, 803 # cryptographic policy files, and standard JCE providers provided with 804 # the Java SE, have been reviewed and approved for export as mass market 805 # encryption item by the US Bureau of Industry and Security. 806 # 807 # Note: This property is currently used by the JDK Reference implementation. 808 # It is not guaranteed to be examined and used by other implementations. 809 # 810 #crypto.policy=unlimited 811 812 # The policy for the XML Signature secure validation mode.
