62/* (From RFC1521 and draft-ietf-dnssec-secext-03.txt)
63 The following encoding technique is taken from RFC 1521 by Borenstein
64 and Freed. It is reproduced here in a slightly edited form for
65 convenience.
66
67 A 65-character subset of US-ASCII is used, enabling 6 bits to be
68 represented per printable character. (The extra 65th character, "=",
69 is used to signify a special processing function.)
70
71 The encoding process represents 24-bit groups of input bits as output
72 strings of 4 encoded characters. Proceeding from left to right, a
73 24-bit input group is formed by concatenating 3 8-bit input groups.
74 These 24 bits are then treated as 4 concatenated 6-bit groups, each
75 of which is translated into a single digit in the base64 alphabet.
76
77 Each 6-bit group is used as an index into an array of 64 printable
78 characters. The character referenced by the index is placed in the
79 output string.

100 16 Q 33 h 50 y
101
102 Special processing is performed if fewer than 24 bits are available
103 at the end of the data being encoded. A full encoding quantum is
104 always completed at the end of a quantity. When fewer than 24 input
105 bits are available in an input group, zero bits are added (on the
106 right) to form an integral number of 6-bit groups. Padding at the
107 end of the data is performed using the '=' character.
108
109 Since all base64 input is an integral number of octets, only the
110 -------------------------------------------------
111 following cases can arise:
112
113 (1) the final quantum of encoding input is an integral
114 multiple of 24 bits; here, the final unit of encoded
115 output will be an integral multiple of 4 characters
116 with no "=" padding,
117 (2) the final quantum of encoding input is exactly 8 bits;
118 here, the final unit of encoded output will be two
119 characters followed by two "=" padding characters, or
120 (3) the final quantum of encoding input is exactly 16 bits;
121 here, the final unit of encoded output will be three
122 characters followed by one "=" padding character.
