Truecrypt is a very good encryption program to keep files password protected. There is a lot of information out there. Please note that as of aproximatly May 2014, the creators of truecrypt shut down their website and are claiming that people do not use it. This is not because it is unreliable, but rather because they are trying to have it officially auditted. We can all still use Truecrypt and it is still very safe. No vulnerabilities or backdoors have been discovered and eventually it will most likely be rereleased. For now you can download it here:
