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 security.provider.10=apple.security.AppleProvider 78 79 # 80 # Sun Provider SecureRandom seed source. 81 # 82 # Select the primary source of seed data for the "SHA1PRNG" and 83 # "NativePRNG" SecureRandom implementations in the "Sun" provider. 84 # (Other SecureRandom implementations might also use this property.) 85 # 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. 89 # 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. 93 # 94 # By default, an attempt is made to use the entropy gathering device 95 # specified by the "securerandom.source" Security property.

See "Java Cryptography Architecture Standard Algorithm Name 449 # Documentation" for information about Standard Algorithm Names. Matching 450 # is performed using a case-insensitive sub-element matching rule. (For 451 # example, in "SHA1withECDSA" the sub-elements are "SHA1" for hashing and 452 # "ECDSA" for signatures.) If the assertion "AlgorithmName" is a 453 # sub-element of the certificate algorithm name, the algorithm will be 454 # rejected during certification path building and validation. For example, 455 # the assertion algorithm name "DSA" will disable all certificate algorithms 456 # that rely on DSA, such as NONEwithDSA, SHA1withDSA. However, the assertion 457 # will not disable algorithms related to "ECDSA". 458 # 459 # A "Constraint" provides further guidance for the algorithm being specified. 460 # The "KeySizeConstraint" requires a key of a valid size range if the 461 # "AlgorithmName" is of a key algorithm. The "DecimalInteger" indicates the 462 # key size specified in number of bits. For example, "RSA keySize <= 1024" 463 # indicates that any RSA key with key size less than or equal to 1024 bits 464 # should be disabled, and "RSA keySize < 1024, RSA keySize > 2048" indicates 465 # that any RSA key with key size less than 1024 or greater than 2048 should 466 # be disabled. Note that the "KeySizeConstraint" only makes sense to key 467 # algorithms. 468 # 469 # Note: This property is currently used by Oracle's PKIX implementation.
