I don't think Python would be a good choice for the basic keystroke logging
utility. A program like this is implemented as a systemwide message hook,
which is a DLL that is loaded into the address space of *every* application.
This is a simple piece of code that should be written in C/C++ to keep it
There are a number of commercial products that do keystroke logging, but the
ones I've seen are intended for spying on someone else's computer
activity--i.e. something your boss might want to put on your computer, not
something you would want to put on your boss's computer!
I find the spying orientation of those products rather distasteful, but
maybe one of them could be used in a more benign way. PC Magazine reviewed
several of them last year:
Some time ago I wrote a similar program for my own use (spying on myself as
it were). Maybe it would be worth cleaning it up and releasing it as open
source. It's actually pretty handy. For example, if I see a file on my
system I don't recognize, I can look back at my log and see what I was
doing--what program I was running that created that file. But I'd be worried
about the privacy implications--I wouldn't want my program being used as
