#
# 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.<n>=<className> 
#
# 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.
#
# <className> 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

#
# Class to instantiate as the system scope:
#
system.scope=sun.security.provider.IdentityDatabase
