         strings of 4 encoded characters.  Proceeding from left to right, a
         24-bit input group is formed by concatenating 3 8bit input groups.
         These 24 bits are then treated as 4 concatenated 6-bit groups, each
         of which is translated into a single digit in the base64 alphabet.

           Special processing is performed if fewer than 24 bits are available
           at the end of the data being encoded.  A full encoding quantum is
           always completed at the end of a body.  When fewer than 24 input bits
           are available in an input group, zero bits are added (on the right)
           to form an integral number of 6-bit groups.  Padding at the end of
           the data is performed using the "=" character.  Since all base64
           input is an integral number of octets, only the following cases can
           arise: (1) the final quantum of encoding input is an integral
           multiple of 24 bits; here, the final unit of encoded output will be
           an integral multiple of 4 characters with no "=" padding, (2) the
           final quantum of encoding input is exactly 8 bits; here, the final
           unit of encoded output will be two characters followed by two "="
           padding characters, or (3) the final quantum of encoding input is
           exactly 16 bits; here, the final unit of encoded output will be three
           characters followed by one "=" padding character.
