++/* (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.
++
++ Table 1: The Base64 Alphabet
++
++ Value Encoding Value Encoding Value Encoding Value Encoding
++ 0 A 17 R 34 i 51 z
++ 1 B 18 S 35 j 52 0
++ 2 C 19 T 36 k 53 1
++ 3 D 20 U 37 l 54 2
++ 4 E 21 V 38 m 55 3
++ 5 F 22 W 39 n 56 4
++ 6 G 23 X 40 o 57 5
++ 7 H 24 Y 41 p 58 6
++ 8 I 25 Z 42 q 59 7
++ 9 J 26 a 43 r 60 8
++ 10 K 27 b 44 s 61 9
++ 11 L 28 c 45 t 62 +
++ 12 M 29 d 46 u 63 /
++ 13 N 30 e 47 v
++ 14 O 31 f 48 w (pad) =
++ 15 P 32 g 49 x
++ 16 Q 33 h 50 y
++
++ 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.
