    • i2osp

      public static byte[] i2osp(BigInteger val, int len)
      Convert a BigInteger value to a byte array of a specified length.
      Parameters:
      val - the BigInteger value to be converted
      len - the length of the resulting byte array
      Returns:
      the byte array representation of the BigInteger value
      Throws:
      IllegalArgumentException - if the value requires more bytes than the assigned length size

    • os2ip

      public static BigInteger os2ip(byte[] val)
      Converts a byte array to a BigInteger.
      Parameters:
      val - the byte array to convert
      Returns:
      the BigInteger representation of the byte array

    • xor

      public static byte[] xor(byte[] arg1, byte[] arg2)
      Performs bitwise XOR operation on two byte arrays.
      Parameters:
      arg1 - the first byte array
      arg2 - the second byte array
      Returns:
      the result of the XOR operation as a new byte array
      Throws:
      NullPointerException - if either arg1 or arg2 is null
      IllegalArgumentException - if arg1 and arg2 have different lengths

    • concatenate

      public static byte[] concatenate(byte[]... arrays)
      Concatenates the supplied arrays into one.
      Parameters:
      arrays - the arrays to concatenate
      Returns:
      a concatenated array
