Class RIPEMD320Digest

  • All Implemented Interfaces:
    Digest, ExtendedDigest, Memoable
    public class RIPEMD320Digest
extends GeneralDigest
    implementation of RIPEMD 320.

    Note: this implementation offers the same level of security as RIPEMD 160.

    • Constructor Detail

      • RIPEMD320Digest

        public RIPEMD320Digest()
        Standard constructor

      • RIPEMD320Digest

        public RIPEMD320Digest​(RIPEMD320Digest t)
        Copy constructor. This will copy the state of the provided message digest.

    • 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.

      • processWord

        protected void processWord​(byte[] in,
                           int inOff)
        Specified by:
        processWord in class GeneralDigest

      • 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 to the IV values.
        Specified by:
        reset in interface Digest
        Overrides:
        reset in class GeneralDigest

      • 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.
