      • encode

         static Array<byte> encode(Array<byte> data)

        encode the input data producing a Hex encoded byte array.

        Returns:

        a byte array containing the Hex encoded data.

      • encode

         static Array<byte> encode(Array<byte> data, int off, int length)

        encode the input data producing a Hex encoded byte array.

        Returns:

        a byte array containing the Hex encoded data.

      • encode

         static int encode(Array<byte> data, OutputStream out)

        Hex encode the byte data writing it to the given output stream.

        Returns:

        the number of bytes produced.

      • encode

         static int encode(Array<byte> data, int off, int length, OutputStream out)

        Hex encode the byte data writing it to the given output stream.

        Returns:

        the number of bytes produced.

      • decode

         static Array<byte> decode(Array<byte> data)

        decode the Hex encoded input data. It is assumed the input data is valid.

        Returns:

        a byte array representing the decoded data.

      • decode

         static Array<byte> decode(String data)

        decode the Hex encoded String data - whitespace will be ignored.

        Returns:

        a byte array representing the decoded data.

      • decode

         static int decode(String data, OutputStream out)

        decode the Hex encoded String data writing it to the given output stream, whitespace characters will be ignored.

        Returns:

        the number of bytes produced.

      • decodeStrict

         static Array<byte> decodeStrict(String str)

        Decode the hexadecimal-encoded string strictly i.e. any non-hexadecimal characters will be considered an error.

        Returns:

        a byte array representing the decoded data.

      • decodeStrict

         static Array<byte> decodeStrict(String str, int off, int len)

        Decode the hexadecimal-encoded string strictly i.e. any non-hexadecimal characters will be considered an error.

        Returns:

        a byte array representing the decoded data.
