public class Cryptix
extends java.security.Provider

This class acts as a security provider for the Java Cryptography Architecture. The mapping between cipher names and classes is stored in the Cryptix.properties file (see CryptixProperties).

SECURITY: In JavaSoft's version of JCE, Provider indirectly extends Hashtable, which means that it would normally be possible to call the put, remove or clear methods to change properties without any security check (also the load method from Properties). This is arguably a design bug in JCA and/or the Properties class.

This class works around the potential security problem by not using the Hashtable superclass. Instead it delegates to CryptixProperties.
