Constructor Detail

MD2Digest

public MD2Digest()

MD2Digest

public MD2Digest(MD2Digest t)
Method Detail

getAlgorithmName

public java.lang.String getAlgorithmName()
return the algorithm name
Specified by:
getAlgorithmName in interface Digest
Returns:
the algorithm name

getDigestSize

public int getDigestSize()
return the size, in bytes, of the digest produced by this message digest.
Specified by:
getDigestSize in interface Digest
Returns:
the size, in bytes, of the digest produced by this message digest.

doFinal

public int doFinal(byte[] out,
                   int outOff)
close the digest, producing the final digest value. The doFinal call leaves the digest reset.
Specified by:
doFinal in interface Digest
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.
Specified by:
reset in interface Digest

update

public void update(byte in)
update the message digest with a single byte.
Specified by:
update in interface Digest
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.
Specified by:
update in interface Digest
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.

processCheckSum

protected void processCheckSum(byte[] m)

processBlock

protected void processBlock(byte[] m)
