    - #### encodeBase64

          public static Writable encodeBase64(java.lang.Byte[] data,
                                              boolean chunked)

      Produce a Writable object which writes the Base64 encoding of the byte array. Calling toString() on the result returns the encoding as a String. For more information on Base64 encoding and chunking see `RFC 4648`.
      Parameters:
        `data` - Byte array to be encoded
        `chunked` - whether or not the Base64 encoded data should be MIME chunked
      Returns:
        object which will write the Base64 encoding of the byte array
      Since:
        1.5.1

    - #### encodeBase64

          public static Writable encodeBase64(java.lang.Byte[] data)

      Produce a Writable object which writes the Base64 encoding of the byte array. Calling toString() on the result returns the encoding as a String. For more information on Base64 encoding and chunking see `RFC 4648`.
      Parameters:
        `data` - Byte array to be encoded
      Returns:
        object which will write the Base64 encoding of the byte array
      Since:
        1.0

    - #### encodeBase64

          public static Writable encodeBase64(byte[] data,
                                              boolean chunked)

      Produce a Writable object which writes the Base64 encoding of the byte array. Calling toString() on the result returns the encoding as a String. For more information on Base64 encoding and chunking see `RFC 4648`.
      Parameters:
        `data` - byte array to be encoded
        `chunked` - whether or not the Base64 encoded data should be MIME chunked
      Returns:
        object which will write the Base64 encoding of the byte array
      Since:
        1.5.7

    - #### encodeBase64

          public static Writable encodeBase64(byte[] data)

      Produce a Writable object which writes the Base64 encoding of the byte array. Calling toString() on the result returns the encoding as a String. For more information on Base64 encoding and chunking see `RFC 4648`.
      Parameters:
        `data` - byte array to be encoded
      Returns:
        object which will write the Base64 encoding of the byte array
      Since:
        1.0

    - #### decodeBase64

          public static byte[] decodeBase64(java.lang.String value)

      Decode the String from Base64 into a byte array.
      Parameters:
        `value` - the string to be decoded
      Returns:
        the decoded bytes as an array
      Since:
        1.0

    - #### encodeHex

          public static Writable encodeHex(java.lang.Byte[] data)

      Produces a Writable that writes the hex encoding of the Byte[]. Calling toString() on this Writable returns the hex encoding as a String. The hex encoding includes two characters for each byte and all letters are lower case.
      Parameters:
        `data` - byte array to be encoded
      Returns:
        object which will write the hex encoding of the byte array
      See Also:
        `Integer.toHexString(int)`

    - #### encodeHex

          public static Writable encodeHex(byte[] data)

      Produces a Writable that writes the hex encoding of the byte[]. Calling toString() on this Writable returns the hex encoding as a String. The hex encoding includes two characters for each byte and all letters are lower case.
      Parameters:
        `data` - byte array to be encoded
      Returns:
        object which will write the hex encoding of the byte array
      See Also:
        `Integer.toHexString(int)`

    - #### decodeHex

          public static byte[] decodeHex(java.lang.String value)

      Decodes a hex string to a byte array. The hex string can contain either upper case or lower case letters.
      Parameters:
        `value` - string to be decoded
      Returns:
        decoded byte array
      Throws:
        `java.lang.NumberFormatException` - If the string contains an odd number of characters or if the characters are not valid hexadecimal values.
