Keylogging

I was wondering if anyone can help to teach me about keylogging.
I have tried a few different programmes but cant get my head around them.
Basicly all i need is a programme that will encrypt the keylogger into something like a word document send it to people and then have there passwords/information e.t.c. sent to me

I don't think that the people in this board will give you a trojan horse maker or something like that, because illegal stuff is not allowed here.
Fuck off and do some researches with google and don't forget that you might get jailed for doing something dumb with a trojan horse.
