      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:

    • update

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

    • update

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

    • reset

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