Method Detail

getAlgorithmName

public java.lang.String getAlgorithmName()

Description copied from interface: Digest

return the algorithm name

Overrides:

getAlgorithmName in class KeccakDigest

Following copied from interface: org.bouncycastle.crypto.Digest

Returns:

the algorithm name

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.

Overrides:

doFinal in class KeccakDigest

Following copied from interface: org.bouncycastle.crypto.Digest

Parameters:

out - the array the digest is to be copied into.

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

doFinal

protected int doFinal(byte[] out,
                      int outOff,
                      byte partialByte,
                      int partialBits)

Overrides:

doFinal in class KeccakDigest
