-/* (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.
