Are you a business owner that sends confidential documents through email? If not - this can still come in good use for individuals. In example, you've changed doctors and you want to give your new physician all your health records.

GPG4Win.org offers a freeware program that lets you both encrypt and digitally sign your emails. I however do not recommend this to computer novices. It does require an advanced understanding to use this application. I tried it several months ago, but I gave up. I decided to try again last week and finally figured it out.

The good side is that it does come with a PDF that explains what to do (in both English and German). In addition to this - you can also test how it works first by exchanging your public keys with an email-based robot. This makes the learning process fun and somewhat easier.

All in all - I'm really happy I've come across this site!
