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.
