++/* (From RFC1521 and draft-ietf-dnssec-secext-03.txt)
++   The following encoding technique is taken from RFC 1521 by Borenstein
++   and Freed.  It is reproduced here in a slightly edited form for
++   convenience.
++
++   A 65-character subset of US-ASCII is used, enabling 6 bits to be
++   represented per printable character. (The extra 65th character, "=",
++   is used to signify a special processing function.)
++
++   The encoding process represents 24-bit groups of input bits as output
++   strings of 4 encoded characters. Proceeding from left to right, a
++   24-bit input group is formed by concatenating 3 8-bit 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.
++
++   Each 6-bit group is used as an index into an array of 64 printable
++   characters. The character referenced by the index is placed in the
++   output string.

++
++   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 quantity.  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.
