Method Detail
-
getAlgorithmName
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(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
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
void reset()
reset the digest back to it's initial state.
-
getByteLength
int getByteLength()
Return the size in bytes of the internal buffer the digest applies it's compression function to.
- Returns:
byte length of the digests internal buffer.
-
copy
Memoable copy()
Produce a copy of this object with its configuration and in its current state.
The returned object may be used simply to store the state, or may be used as a similar object starting from the copied state.
