Examples of org.bouncycastle.crypto.Digest.doFinal()

org.bouncycastle.crypto.Digest.doFinal()
close the digest, producing the final digest value. The doFinal call leaves the digest reset. @param out the array the digest is to be copied into. @param outOff the offset into the out array the digest is to start at.

            Digest  dig = dgOut.getDigest();
            byte[]  hash = new byte[dig.getDigestSize()];
    
            dig.doFinal(hash, 0);
    
            cOut.write(hash);
    
            cOut.close();
