    • getAlgorithmName

      public String getAlgorithmName()
      Description copied from interface: Digest
      return the algorithm name
      Returns:
      the algorithm name
    • getByteLength

      public int getByteLength()
      Description copied from interface: ExtendedDigest
      Return the size in bytes of the internal buffer the digest applies it's compression function to.
      Specified by:
      getByteLength in interface ExtendedDigest
      Returns:
      byte length of the digests internal buffer.
    • getDigestSize

      public int getDigestSize()
      Description copied from interface: Digest
      return the size, in bytes, of the digest produced by this message digest.
      Specified by:
      getDigestSize in interface Digest
      Returns:
      the size, in bytes, of the digest produced by this message digest.
    • init

      public void init(Kangaroo.KangarooParameters pParams)
      Initialise the digest.
      Parameters:
      pParams - the parameters
    • update

      public void update(byte pIn)
      Description copied from interface: Digest
      update the message digest with a single byte.
      Specified by:
      update in interface Digest
      Parameters:
      pIn - the input byte to be entered.
    • update

      public void update(byte[] pIn, int pInOff, int pLen)
      Description copied from interface: Digest
      update the message digest with a block of bytes.
      Specified by:
      update in interface Digest
      Parameters:
      pIn - the byte array containing the data.
      pInOff - the offset into the byte array where the data starts.
      pLen - the length of the data.
    • doFinal

      public int doFinal(byte[] pOut, int pOutOffset)
      Description copied from interface: Digest
      close the digest, producing the final digest value. The doFinal call leaves the digest reset.
      Specified by:
      doFinal in interface Digest
      Parameters:
      pOut - the array the digest is to be copied into.
      pOutOffset - the offset into the out array the digest is to start at.
    • doFinal

      public int doFinal(byte[] pOut, int pOutOffset, int pOutLen)
      Description copied from interface: Xof
      Output the results of the final calculation for this digest to outLen number of bytes.
      Specified by:
      doFinal in interface Xof
      Parameters:
      pOut - output array to write the output bytes to.
      pOutOffset - offset to start writing the bytes at.
      pOutLen - the number of output bytes requested.
      Returns:
      the number of bytes written
    • doOutput

      public int doOutput(byte[] pOut, int pOutOffset, int pOutLen)
      Description copied from interface: Xof
      Start outputting the results of the final calculation for this digest. Unlike doFinal, this method will continue producing output until the Xof is explicitly reset, or signals otherwise.
      Specified by:
      doOutput in interface Xof
      Parameters:
      pOut - output array to write the output bytes to.
      pOutOffset - offset to start writing the bytes at.
      pOutLen - the number of output bytes requested.
      Returns:
      the number of bytes written
    • reset

      public void reset()
      Description copied from interface: Digest
      reset the digest back to it's initial state.
      Specified by:
      reset in interface Digest
