Interface I_MsgSecurityInterceptor

All Known Subinterfaces:

All Known Implementing Classes:

public interface I_MsgSecurityInterceptor

Interface declaring methods to intercept messages in the security layer to allow crypt/encrypt etc. messages before sending.

If for example the server security plugin crypts messages with rot13, we need to decrypt it on the client side with the same algorithm. This is done here.

The reason is for clients to access xmlBlaster transparently from the authentication method

For every plugin type you need, you need on instance of this class.
