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.
-
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 chaining variables to the IV values.
-
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.
-
reset
void reset(Memoable other)
Restore a copied object state into this object.
Implementations of this method should try to avoid or minimise memory allocation to perform the reset.
- Parameters:
other
- an object originally copied from an object of the same type as this instance.
-
getEncodedState
Array<byte> getEncodedState()
Return an encoded byte array for the digest's internal state
- Returns:
an encoding of the digests internal state.
