public Memoable copy()

Implements abstract org.bouncycastle.crypto.digests.GOST3411_2012Digest.copy.

Implements org.bouncycastle.util.Memoable.copy.

Doc from org.bouncycastle.util.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.

doFinalback to summary
public int doFinal(byte[] out, int outOff)

Overrides org.bouncycastle.crypto.digests.GOST3411_2012Digest.doFinal.

Implements org.bouncycastle.crypto.Digest.doFinal.

Doc from org.bouncycastle.crypto.Digest.doFinal.

close the digest, producing the final digest value. The doFinal call leaves the digest reset.

Parameters
out:byte[]

the array the digest is to be copied into.

outOff:int

the offset into the out array the digest is to start at.
