Interface Digester

All Known Subinterfaces:

DigestBuffer

All Known Implementing Classes:

DigestBufferJre, DigesterJre

public interface Digester

A simple interface for creating digests of bytes; this is used primarily so we can have shared code that is able to invoke Digest operations, without accessing any potentially unsupported classes in a given environment.

This also allows the digest function to be easily pluggable, so end users can select the digest algorithm to use. The default implementation uses java core MD5 hashing.

This interface should be instantiated via X_Inject.instance(Digester.class), as a digester needs to store internal state, it cannot be a singleton.
