      • encodeToChar

        public static char[] encodeToChar​(byte[] sArr)
        Encodes a raw byte array into a BASE64Url char[] representation i accordance with RFC 2045.
        Parameters:
        sArr - The bytes to convert. If null or length 0 an empty array will be returned.
        Returns:
        A BASE64Url encoded array. Never null.

      • decodeFast

        public static byte[] decodeFast​(char[] sArr)
        Decodes a BASE64Url encoded char array that is known to be reasonably well formatted. The preconditions are:
        + The array must have no line separators at all (one line).
        + The array may not contain illegal characters within the encoded string
        + The array CAN have illegal characters at the beginning and end, those will be dealt with appropriately.
        Parameters:
        sArr - The source array. Length 0 will return an empty array. null will throw an exception.
        Returns:
        The decoded array of bytes. May be of length 0.

      • encodeToByte

        public static byte[] encodeToByte​(byte[] sArr)
        Encodes a raw byte array into a BASE64Url byte[] representation i accordance with RFC 2045.
        Parameters:
        sArr - The bytes to convert. If null or length 0 an empty array will be returned.
        Returns:
        A BASE64Url encoded array. Never null.

      • decodeFast

        public static byte[] decodeFast​(byte[] sArr)
        Decodes a BASE64Url encoded byte array that is known to be reasonably well formatted. The preconditions are:
        + The array must have no line separators at all (one line).
        + The array may not contain illegal characters within the encoded string
        + The array CAN have illegal characters at the beginning and end, those will be dealt with appropriately.
        Parameters:
        sArr - The source array. Length 0 will return an empty array. null will throw an exception.
        Returns:
        The decoded array of bytes. May be of length 0.

      • encodeToString

        public static String encodeToString​(byte[] sArr)
        Encodes a raw byte array into a BASE64Url String representation i accordance with RFC 2045.
        Parameters:
        sArr - The bytes to convert. If null or length 0 an empty array will be returned.
        Returns:
        A BASE64Url encoded array. Never null.

      • decodeFast

        public static byte[] decodeFast​(String s)
        Decodes a BASE64Url encoded string that is known to be reasonably well formatted. The preconditions are:
        + The array must have no line separators at all (one line).
        + The array may not contain illegal characters within the encoded string
        + The array CAN have illegal characters at the beginning and end, those will be dealt with appropriately.
        Parameters:
        s - The source string. Length 0 will return an empty array. null will throw an exception.
        Returns:
        The decoded array of bytes. May be of length 0.
