String	getAlgorithmName() return the algorithm name
int	getByteLength()
int	getDigestSize() return the size, in bytes, of the digest produced by this message digest.
protected void	processBlock(byte[] m)
protected void	processCheckSum(byte[] m)
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.

Constructor Detail

MD2Digest

public MD2Digest()

MD2Digest

public MD2Digest(MD2Digest t)

Method Detail

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.

getAlgorithmName

public String getAlgorithmName()

return the algorithm name

Returns: the algorithm name

getByteLength

public int getByteLength()

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.

processBlock

protected void processBlock(byte[] m)

processCheckSum

protected void processCheckSum(byte[] m)

reset

public void reset()

reset the digest back to it's initial state.

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.
