      Description copied from interface: Digest
      return the algorithm name
      Specified by:
      getAlgorithmName in interface Digest
      Returns:
      the algorithm name

    • getDigestSize

      public int getDigestSize()
      Description copied from interface: Digest
      return the size, in bytes, of the digest produced by this message digest.
      Specified by:
      getDigestSize in interface Digest
      Returns:
      the size, in bytes, of the digest produced by this message digest.

    • update

      public void update(byte in)
      Description copied from interface: Digest
      update the message digest with a single byte.
      Specified by:
      update in interface Digest
      Parameters:
      in - the input byte to be entered.

    • update

      public void update(byte[] message, int offset, int len)
      Description copied from interface: Digest
      update the message digest with a block of bytes.
      Specified by:
      update in interface Digest
      Parameters:
      message - the byte array containing the data.
      offset - the offset into the byte array where the data starts.
      len - the length of the data.

    • doFinal

      public int doFinal(byte[] out, int outOff)
      Description copied from interface: Digest
      close the digest, producing the final digest value. The doFinal call leaves the digest reset.

      doFinal in interface Digest
      Parameters:
      out - the array the digest is to be copied into.
      outOff - the offset into the out array the digest is to start at.

    • reset

      public void reset()
      Description copied from interface: Digest
      reset the digest back to it's initial state.
      Specified by:
      reset in interface Digest

    • getByteLength

      public int getByteLength()
      Description copied from interface: ExtendedDigest
      Return the size in bytes of the internal buffer the digest applies it's compression function to.
      Specified by:
      getByteLength in interface ExtendedDigest
      Returns:
      byte length of the digests internal buffer.
