# # This is the "master security properties file". # # In this file, various security properties are set for use by # java.security classes. 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: Statically registered Provider subclasses are instantiated # when the system is initialized. 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=com.sun.net.ssl.internal.ssl.Provider security.provider.3=com.sun.rsajca.Provider security.provider.4=com.sun.crypto.provider.SunJCE security.provider.5=sun.security.jgss.SunProvider # # Select the source of seed data for SecureRandom. By default an # attempt is made to use the entropy gathering device specified by # the securerandom.source property. If an exception occurs when # accessing the URL then the traditional system/thread activity # algorithm is used. # On Windows systems, the URL file:/dev/random enables use of the # Microsoft CryptoAPI seed functionality. # securerandom.source=file:/dev/random # # The entropy gathering device is described as a URL and can # also be specified with the property "java.security.egd".
