As I read the article, last time it took 9 years to generalize the method used for the special number to any number. Now, my key is valid for one year, and I expect messages protected by that key to be a secret for maybe a year longer, that means that at the current rate I'll be able to use my card for at least 5 more years end maybe longer. And then still, it takes 11 months on a huge cluster of computers to factor out my key, or to compare, all of the compute power available in this country for a substantial amount of time. I guess you're right, if the nsa is after you, you need stronger keys. If it's just anybody else, I'd say you'll be safe for a few more years. Your ssl certificates will have expired by that time, and maybe a 2048 bit openpgp card will be available (at a reasonable prise). > Snoken > _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users -- Met vriendelijke groeten, Remco Post SARA - Reken- en Netwerkdiensten http://www.sara.nl High Performance Computing Tel. +31 20 592 3000 Fax. +31 20 668 3167 PGP Key fingerprint = 6367 DFE9 5CBC 0737 7D16 B3F6 048A 02BF DC93 94EC "I really didn't foresee the Internet.
