    • convertToHexString

      public static String convertToHexString(byte[] toBeConverted)
      Take the supplied byte array and convert it to a hex encoded String.
      Parameters:
      toBeConverted - - the bytes to be converted.
      Returns:
      the hex encoded String.

    • convertToHexBytes

      public static byte[] convertToHexBytes(byte[] toBeConverted)
      Take the supplied byte array and convert it to to a byte array of the encoded hex values.

      Each byte on the incoming array will be converted to two bytes on the return array.

      Parameters:
      toBeConverted - - the bytes to be encoded.
      Returns:
      the encoded byte array.

    • convertFromHex

      public static byte[] convertFromHex(char[] toConvert)
      Take the incoming character of hex encoded data and convert to the raw byte values.

      The characters in the incoming array are processed in pairs with two chars of a pair being converted to a single byte.

      Parameters:
      toConvert - - the hex encoded String to convert.
      Returns:
      the raw byte array.

    • toByte

      private static byte toByte(char[] toConvert, int pos)

    • convertFromHex

      public static byte[] convertFromHex(String toConvert)
      Take the incoming String of hex encoded data and convert to the raw byte values.

      The characters in the incoming String are processed in pairs with two chars of a pair being converted to a single byte.

      Parameters:
      toConvert - - the hex encoded String to convert.
      Returns:
      the raw byte array.
