public interface Digest

interface that a message digest conforms to.

Method Summary
`int` | `doFinal(byte[] out, int outOff)` close the digest, producing the final digest value.
`java.lang.String` | `getAlgorithmName()` return the algorithm name
`int` | `getDigestSize()` return the size, in bytes, of the digest produced by this message digest.
`void` | `reset()` reset the digest back to it's initial state.
`void` | `update(byte in)` update the message digest with a single byte.
`void` | `update(byte[] in, int inOff, int len)` update the message digest with a block of bytes.

Method Detail

### getAlgorithmName

    public java.lang.String getAlgorithmName()

  return the algorithm name

  Returns:
    the algorithm name

### getDigestSize

    public int getDigestSize()

  return the size, in bytes, of the digest produced by this message digest.

  Returns:
    the size, in bytes, of the digest produced by this message digest.

### update

    public void update(byte in)

  update the message digest with a single byte.

  Parameters:
    `in` - the input byte to be entered.

### update

    public void update(byte[] in,
                       int inOff,
                       int len)

  update the message digest with a block of bytes.

  Parameters:
    `in` - the byte array containing the data.
    `inOff` - the offset into the byte array where the data starts.
    `len` - the length of the data.

### doFinal

    public int doFinal(byte[] out,
                       int outOff)

  close the digest, producing the final digest value. The doFinal call leaves the digest reset.

  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()

  reset the digest back to it's initial state.
