Constructor Detail

### SHA384Digest

    public SHA384Digest()

  Standard constructor

### SHA384Digest

    public SHA384Digest(SHA384Digest t)

  Copy constructor. This will copy the state of the provided message digest.

Method Detail

### getAlgorithmName

    public java.lang.String getAlgorithmName()

  Description copied from interface: `Digest`
  return the algorithm name

  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.

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

### 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.

  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 chaining variables

  Specified by:
    `reset` in interface `Digest`
  Overrides:
    `reset` in class `LongDigest`
