What Kind of File is the Attachment signature.asc?

The file signature.asc is my digital signature of the email.

What is a Digital Signature?

A digital signature ensures three features my cryptographic practices:

The message was composed by me (Nils Keller).
This helps you ensuring I am the author of the message. Nobody else can send a message signed by me.
The message was not changed on its way.
This guarantees that nobody intercepted and changed or even completely exchanged the message.
I cannot deny being the sender of this message.
This feature is quite academical, but can be clarified by an example: Should a signed message be used against me in a legal case, I cannot claim not having sent this message.

What is the Benefit?

The signature itself allows using the said features. This is indeed interesting, but not that spectacular yet. But with this I want to campaign for the usage of the related encryption of emails. Governmental actions like the US Echelon Project or the Telecommunications data retention agreed by the European Union in February 2006 threaten to wipe out unobserved private communication. We can resist this by encrypting our email communication.

How can I sign and encrypt emails?

The simplest method for encrypting private emails offers OpenPGP. This is a program dealing with signing, encryption and decryption of emails. In order to conveniently using it, it should be integrated in your email client (sadly, using it is still inconvenient at the moment). The following options exist for wide-spread email clients:

The page GnuPG lists more possibilities for other email clients.

What do I need from you?

In order to send encrypted messages to me or verify my signature you need my public key. You can either download the key as a file or transfer it via the clipboard (at the said links you'll find instructions how to import the key. Email me if you have any questions!)

Help to protect our privacy – as long as it is left!
