GnuPG public key
If you want to send me encrypted emails or files you can use my GnuPG (GNU Privacy Guard) public key.
With GnuPG, which is a free software tool, you can encrypt a text file, so that is only readable by a specific person. For this you need the persons public key. It can also be used to sign a file. With your signature you authenticate, that a file is really from you and that it was not altered afterwards by anyone.
There are plug ins available for most major email clients. With Apple Mail I am using GPGMail which works quite well. On Linux I am using the free Evolution mail client, which has build-in GnuPG support.
