Class SHA224Digest


  • public class SHA224Digest
    extends java.security.MessageDigest
    SHA-224 as described in RFC 3874. This introduces the SHA224 Digest which has been omitted from the JDK java.security. This implementation has been borrowed from the Bouncy Castle implementation of SHA2 algorithms. Since they are MIT Licensed, they are compatible with this project.
