      delimiter - a delimiter that is placed between every two bytes
      Returns:
      the corresponding hex string

    • bytesToHex

      public static String bytesToHex(byte[] bytes)
      Converts a byte array into a hex string (in format "0123456789ABCDEF").
      Parameters:
      bytes - the byte array
      Returns:
      the corresponding hex string

    • byteToHex
