Email is as secure as a normal post card, i.e. not secure at all. On its way through the internet, system administrators, hackers and security services can read and change its contents, without leaving a trace.
To prevent from this, emails can be encrypted. The german ministry of the interior provides the necessary software for free.
You need our public key to encrypt your emails to us. Then you can be sure your mail is only read by us. Please click the key symbol in the upper right corner to download our public key.
