- 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.
