public int doFinal(byte[] out, int outOff)

Overrides org.bouncycastle.crypto.digests.KeccakDigest.doFinal.

Implements 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.

public String getAlgorithmName()

Overrides org.bouncycastle.crypto.digests.KeccakDigest.getAlgorithmName.

Implements org.bouncycastle.crypto.Digest.getAlgorithmName.

Doc from org.bouncycastle.crypto.Digest.getAlgorithmName.

return the algorithm name

Returns:String: the algorithm name
