Analyzing key server data

[Hanno Böck]

Hi,

I think this could be interesting for a couple of people:

I had a project running in private for quite a while, I now published
the details: I wrote a script that analyzes the dumps from key servers
and puts the crypto values into a mysql database.

This can be used to search for vulnerable keys or signatures on large
scale. I did this for two potential threats: DSA signatures with
duplicate k values and RSA keys with shared factors.

The overall result is a good one: It seems OpenPGP implementations with
completely broken random number generators exist, but they are a rare
thing.
