Method Detail
-
getAlgorithmName
public java.lang.String getAlgorithmName()
Description copied from interface:Digest
return the algorithm name- Returns:
- the algorithm name
-
getDigestSize
public int getDigestSize()
Description copied from interface:Digest
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
public int doFinal(byte[] out, int outOff)
Description copied from interface:Digest
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
public void reset()
reset the chaining variables- Specified by:
reset
in interfaceDigest
- Overrides:
reset
in classLongDigest
-
copy
public Memoable copy()
Description copied from interface:Memoable
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
public void reset(Memoable other)
Description copied from interface:Memoable
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 originallycopied
from an object of the same type as this instance.
-
getEncodedState
public byte[] getEncodedState()
Description copied from interface:EncodableDigest
Return an encoded byte array for the digest's internal state- Returns:
- an encoding of the digests internal state.
