I am looking for open source projects with focus on security to contribute to. I am no security person but I wanted to learn about security and from times to times I want to give back some of what I took from open source community. I would prefer to contribute to security because it seems to be one of major and most problematic parts of software world. I also like to start with simple bite-size bugs/issues/features.
tl;dr Are there any open source security projects with bite-size issues to fix?
I couldn't find any USD donation button, which is quite strange. They also don't have a donate button on their site. You can donate here, though, and to a few other projects, too:

There's also these guys here - but I couldn't find any donate button. Jesus, why are they making it so hard to give them money?

You could also donate EFF, which is funding some cool projects such as HTTPS Everywhere, Privacy Badger and soon the free certificate authority https://letsencrypt.org/.
