The last entries - in the list may not produce 4 integers, - a trailing 2 character group gives 3 integers, - while a trailing single character gives 2 integers. b `shiftL` 12 ) in int4_char3 = - Convert triplets of characters to - 4 base64 integers. ![]() 8bit means that the lines are short, but there may be non-ASCII characters (. If encode is TRUE, a character vector with a class named base64. c `shiftL` 6 ) in int4_char3 = let n = ( a `shiftL` 18. 7bit means that the data is all represented as short lines of US-ASCII data.

Hack Alert: In the last entry of the answer, the upper 8 bits encode - the integer number of 6bit groups encoded in that integer, ie 1, 2, 3. Char ( chr, ord ) encodeArray :: Array Int Char encodeArray = array ( 0, 64 ) - Convert between 4 base64 (6bits ea) integers and 1 ordinary integer (32 bits) - clearly the upmost/leftmost 8 bits of the answer are 0. } module Base64 ( encode, decode, chop72 ) where import Data.
