      • encodeBase64

        public static char[] encodeBase64​(byte[] data)

        Encodes the passed byte array using the base64 rules. The base64 encoding schema is performed by grouping the bytes in to 6-bit quantities and then encoding them.

        For more information see RFC1341 for the format used for base64 encoding.

        Parameters:
        data - The input byte array
        Returns:
        The converted data in a character stream.

      • decodeBase64

        public static byte[] decodeBase64​(char[] data)

        Decodes a character array into the corresponding byte array. The buffer must be an intergral number of 4 character. I.E. size mod 4 is equal to zero or an exception will be thrown. Likewise, if there is an invalid character in the input array then an exception will be thrown.

        Parameters:
        data - The data stream to be filtered.
        Returns:
        The coverted array of bytes.
        Throws:
        java.lang.IllegalArgumentException - Thrown if an invalid buffer that cannot be decoded is passed.
