I'll reply to a part that I think I understood:

Some quick reflex actions on the above part:

If the string size does not change, put it into a temporary variable.

j already shows if you got three characters, no need to ask tripple
(triplet?) for it's size.

iterate over "aString , '\0\0\0'", you'll get your padding at the end
for free without extra checks

gotta go now,
s.

You're repeatedly grabbing triplets from the string and are looking
every time if you really got three characters, right?
