Public Constructors

public MD2Digest ()

public MD2Digest (MD2Digest t)

Public Methods

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.

public String getAlgorithmName ()

return the algorithm name

Returns
  • the algorithm name

public int getByteLength ()

Return the size in bytes of the internal buffer the digest applies it's compression function to.

Returns
  • byte length of the digests internal buffer.

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.

public void reset ()

reset the digest back to it's initial state.

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.

public void update (byte in)

update the message digest with a single byte.

Parameters
in the input byte to be entered.

Protected Methods

protected void processBlock (byte[] m)

protected void processCheckSum (byte[] m)
