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