It's an existing ssh key.

I tried it but it didn't work as expected:
$ ssh-add .ssh/id_dsa
Enter passphrase for .ssh/id_dsa: 
Identity added: .ssh/id_dsa (.ssh/id_dsa)
But ssh-add -l didn't list it. Through further testing I found out it
was a problem with my ssh key:
$ ssh-keygen -l -f .ssh/id_dsa.pub 
2048 [fingerprint] .ssh/id_dsa.pub

Don't ask me how I generated this key. As I can use this key with ssh I
didn't suspect it as the problem. I now generated a new 2048 bit RSA key
and it works now.

Thanks for your help,

Michael
