Sorry, They didn't crack them. They exposed a flaw in md5 so they could replicate the certificate hash. 

It wouldn't prevent them but it would at least slow them down and maybe make them move to a easier target.

Peoples data is important and deserves to be protected, IMO.

This can protect the data in the database from sql injections from rouge plugins and miscoded plugins(This seems to be a huge problem, if you read the sec lists in the past week. There have been over 10 new exploits found for different plugins). Have to know the keys to decode the data. CCC(those german guys are pretty bad has already proven that SSL certs can be cracked and replicated on the fly with a cluster of ps3 systems, http://hackaday.com/2008/12/30/25c3-hackers-completely-break-ssl-using-200-ps3s/ .
