      • byteArrayToHexString

        public static String byteArrayToHexString​(byte[] in,
                                                  int start,
                                                  int length)
        Creates a string representation of the supplied byte array in Hexidecimal format
        Parameters:
        in - the byte array to convert to a hex string.
        start - where to begin in the array
        length - how many bytes from the array to include in the hexidecimal representation
        Returns:
        a string containing the hexidecimal representation of the requested bytes from the array
      • byteArrayToHexString

        public static String byteArrayToHexString​(byte[] in)
        Creates a string representation of the supplied byte array in Hexidecimal format
        Parameters:
        in - the byte array to convert to a hex string.
        Returns:
        a string containing the hexidecimal representation of the array
      • hexToByteArray

        public static byte[] hexToByteArray​(String hexString)
        Convert a hex string into an array of bytes. The string is expected to consist entirely of valid Hex characters i.e. 0123456789abcdefABCDEF. The array is calculated by traversing the string from from left to right, ignoring whitespace. Every 2 valid hex chars will constitute a new byte for the array. If the string is uneven then it the last byte will be padded with a '0'.
        Parameters:
        hexString - String to be converted
      • isHexChar

        public static boolean isHexChar​(char current)
