doFinal
public int doFinal(byte[] out,
int outOff)
close the digest, producing the final digest value. The doFinal
call leaves the digest reset.
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
- the algorithm name
getDigestSize
public int getDigestSize()
return the size, in bytes, of the digest produced by this message digest.
- the size, in bytes, of the digest produced by this message digest.
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.
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.
in
- the byte array containing the data.inOff
- the offset into the byte array where the data starts.len
- the length of the data.
