# # This is the "master security properties file". # # An alternate java.security properties file may be specified # from the command line via the system property # # -Djava.security.properties= # # This properties file appends to the master security properties file. # If both properties files specify values for the same key, the value # from the command-line properties file is selected, as it is the last # one loaded. # # Also, if you specify # # -Djava.security.properties== (2 equals), # # then that properties file completely overrides the master security # properties file. # # To disable the ability to specify an additional properties file from # the command line, set the key security.overridePropertiesFile # to false in the master security properties file.

This is where users can statically register # Cryptography Package Providers ("providers" for short). The term # "provider" refers to a package or set of packages that supply a # concrete implementation of a subset of the cryptography aspects of # the Java Security API. A provider may, for example, implement one or # more digital signature algorithms or message digest algorithms. # # Each provider must implement a subclass of the Provider class. # To register a provider in this master security properties file, # specify the Provider subclass name and priority in the format # # security.provider.= # # This declares a provider, and specifies its preference # order n. The preference order is the order in which providers are # searched for requested algorithms (when no specific provider is # requested). The order is 1-based; 1 is the most preferred, followed # by 2, and so on. # # must specify the subclass of the Provider class whose # constructor sets the values of various properties that are required # for the Java Security API to look up the algorithms or other # facilities implemented by the provider. # # There must be at least one provider specification in java.security. # There is a default provider that comes standard with the JDK. It # is called the "SUN" provider, and its Provider subclass # named Sun appears in the sun.security.provider package. Thus, the # "SUN" provider is registered via the following: # # security.provider.1=sun.security.provider.Sun # # (The number 1 is used for the default provider.) # # Note: Providers can be dynamically registered instead by calls to # either the addProvider or insertProviderAt method in the Security # class. # # List of providers and their preference orders (see above): # security.provider.1=sun.security.provider.Sun security.provider.2=sun.security.rsa.SunRsaSign security.provider.3=sun.security.ec.SunEC security.provider.4=com.sun.net.ssl.internal.ssl.Provider security.provider.5=com.sun.crypto.provider.SunJCE security.provider.6=sun.security.jgss.SunProvider security.provider.7=com.sun.security.sasl.Provider security.provider.8=org.jcp.xml.dsig.internal.dom.XMLDSigRI security.provider.9=sun.security.smartcardio.SunPCSC # # Sun Provider SecureRandom seed source. # # Select the primary source of seed data for the "SHA1PRNG" and # "NativePRNG" SecureRandom implementations in the "Sun" provider. # (Other SecureRandom implementations might also use this property.) # # On Unix-like systems (for example, Solaris/Linux/MacOS), the # "NativePRNG" and "SHA1PRNG" implementations obtains seed data from # special device files such as file:/dev/random. # # On Windows systems, specifying the URLs "file:/dev/random" or # "file:/dev/urandom" will enable the native Microsoft CryptoAPI seeding # mechanism for SHA1PRNG. # # By default, an attempt is made to use the entropy gathering device # specified by the "securerandom.source" Security property.

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