  • Method Details

    • cryptoGenericHashKeygen

      void cryptoGenericHashKeygen(byte[] k)
      Generate a key. Store the key in k.
      Parameters:
      k - A place to store the generated key of size GenericHash.KEYBYTES. Though, it may be between GenericHash.KEYBYTES and GenericHash.KEYBYTES_MAX.

    • cryptoGenericHash

      boolean cryptoGenericHash(byte[] out, int outLen, byte[] in, long inLen, byte[] key, int keyLen)
      Hash a byte array.
      Parameters:
      out - A place to store the resulting byte array. You may choose the output size, however the minimum recommended output size is GenericHash.BYTES. You may also specify a value between GenericHash.BYTES_MIN and GenericHash.BYTES_MAX.
      outLen - Size of out.
      in - The text to hash.
      inLen - The size of in.
      key - The key generated by cryptoGenericHashKeygen(byte[]).
      keyLen - The length of the key.
      Returns:
      True if successfully hashed.
