Hi,

yesterday I tried to verify the Debian DVD image that I downloaded.

I did not want to rely on the fingerprints for the public keys used to sign the 
file with the hashes, because I think that I can not fully trust the 
information shown to me on a web page when it is encrypted with a Let's Encrypt 
certificate.

So I went for the Web of Trust.

As I did not use PGP/GPG for many years I needed some time to learn and find 
out that GPG is not capable of automatically finding the path between a public 
key used to verify a signature and the trusted public keys that are already in 
my keyring. In my case these trusted keys are the two keys from the 
"Kryptokampagne" of c't that I downloaded and checked using the fingerprints 
published in the magazine. I was nearly there to give up when I finally found 

https://pgp.cs.uu.nl

a web page offering exactly what I needed: Giving it two keys it showed me that 
I need to add only 1 additional key to my keyring in order to complete the Web 
of Trust and make one of the keys used to sign the Debian CD key valid.

I propose that you add at least the information about this web page to the 
verification page.

Further instructions how to use GPG to verify a signature, how to find out and 
add needed public keys to the keyring, how to actually know that a verification 
is successful (the messages of GPG are not self-explanatory and the man page 
was unclear too) are certainly welcome too. You could even go so far as to 
supply a keyring that allows a successful verification after checking and 
trusting certain "root" keys like the ones from c't.

Thanks a lot.

Best Regards

 Martin Glaser
