  • Constructor Details

    • RIPEMD128Digest

      public RIPEMD128Digest()
      Standard constructor

    • RIPEMD128Digest

      public RIPEMD128Digest(CryptoServicePurpose purpose)

    • RIPEMD128Digest

      public RIPEMD128Digest(RIPEMD128Digest t)
      Copy constructor. This will copy the state of the provided message digest.

  • Method Details

    • getAlgorithmName

      public 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

    • processLength

      protected void processLength(long bitLength)
      Specified by:
      processLength 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

    • processBlock

      protected void processBlock()
      Specified by:
      processBlock 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.

    • cryptoServiceProperties

      protected CryptoServiceProperties cryptoServiceProperties()
      Specified by:
      cryptoServiceProperties in class GeneralDigest
