Method Detail
-
getAlgorithmName
java.lang.String getAlgorithmName()
return the algorithm name- Returns:
- the algorithm name
-
getDigestSize
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.
-
update
void update(byte in)
update the message digest with a single byte.- Parameters:
in
- the input byte to be entered.
-
update
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.
-
doFinal
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.
-
reset
void reset()
reset the digest back to it's initial state.
