That's overreacting. What happens if Gentoo makes a similar mistake with RSA keys, will we ban them, too? DSA is a decent technology. > I've heard rumblings that DSA keys are weaker for other reasons, but > I've not seen any good explanations. Hearsay, your honour! On the contrary, I've heard that DSA gathers at 1024 bits at least as much entropy as RSA with 2048, and DSA was the recommended "new" algorithm half a decade ago. Currently RSA and DSA are equal up. Please restore the possibility to use DSA. People doing so are knowledgable enough (DSA is not the default with ssh-keygen) to have dealt with any keys they may have created on Debian systems during the time window their rnd gen was bad. If they haven't you won't save them anyway. > In any case, it's probably a good idea to regenerate your SSH keys > every now and then, I know I had been using mine FAR too long. There are different opinions on this as well. If you access several dozens of systems scattered world-wide in differently administered environments you will be glad not to have to change the keys that often and to use only a few keys, and not one for every host. -- Axel.Thimm at ATrpms.net
