/* (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.
