Uuencoding transforms a binary file into a printable text file by splitting the file up into groups of 3 bytes (24 bits), which is then split into 4 6-bit values. Each 6-bit value is incremented by 32 which maps the values onto the printable ASCII values. Converting every 3 binary characters into 4 printable characters.
Extended uuencode & uudecode: xxuuencode & xxuudecode
xxencode decomposes the file the same as uuencode, breaking every 3 bytes into 4 6-bit values. The 6-bit values (0, 1, 2, 3, ...63) are mapped 1-to-1 onto the printable characters:
+-0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxy z
Base64 encoding, a MIME standard, works similar to extended uuencoding except that it uses a different 1-to-1 printable character mapping sequence:
ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+ /
