Last addendum, I promise:
This is factually incoherent. Rainbow tables attack hash functions: they don't attack signature algorithms. If someone was interested in using rainbow tables against a signature algorithm they'd make sure to carefully specify what hash algorithm was used, because rainbow tables have to be made specifically for a hash algorithm.
A question got raised: "Wouldn't this give you a random message that the signature would also work for? Could it even be used to forge a useful message?" First question: yes. Second question: probably not. Maybe, depending on how the signature was being used. There are good reasons why nobody attacks signatures with rainbow tables. I apologize for not making this clear in my earlier email -- I thought it went without saying, but maybe the clarification is useful. _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
