    • 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 interface Digest
        Overrides:
        reset in class LongDigest

      • 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 originally copied 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.
