Sven Köppel: Contact

I'm most happy if you drop me a plain old E-Mail at svenk@svenk.org.

Or send something encrypted instead

Since convenient encrypted mail is somewhat dead, why not roll out our own crypto instead in order to bootstrap for some secure communication channel.

Just go ahead, use things which are public available anways, such as my SSH public keys at github:

echo "Prepare some secret message" > secret.msg.txt
wget https://github.com/svenk.keys
tail -n1 svenk.keys > last.pub.key
ssh-keygen -f last.pub.key -e -m PKCS8  > svenk.pub.pem
echo "Hi Sven, I'm writing you an encrypted message using your SSH public key:" > msg.txt
cat last.pub.key >> msg.txt
echo "-----BEGIN SSH ENCRYPTED MESSAGE-----" >> msg.txt
cat secret.msg.txt | openssl rsautl -encrypt -pubin -inkey svenk.pub.pem -ssl | openssl base64 >> msg.txt
echo "-----END SSH ENCRYPTED MESSAGE-----" >> msg.txt
echo "Now go on and write this mail to sven:"
echo
cat msg.txt

The above most likely works on any standard unix-like system with OpenSSH and OpenSSL installed.
