Class MessageDigest
java.lang.Objectorg.apache.java.security.MessageDigest
- Direct Known Subclasses:
- MD5
Deprecated. Use the java.security package.
- public abstract class MessageDigest
- extends java.lang.Object
This interface abstracts a message digest algorithm.
Note: even if standard Java 1.1 APIs already provide a
message digest implementation, this class is used on those Java
runtime environments (like Kaffe) where the package
java.security is highly improbable to be found.
