[Python-Dev] Hash collision security issue (now public) (original) (raw)

Hi,

It seems to me that half the folk discussing this issue want a super-strong, resist-all-hypothetical-attacks hash with little regard to performance. The other half want no change or a change that will have no observable effect. (I may be exaggerating a little.)

Can I propose the following, half-way proposal:

  1. Since there is a published vulnerability, that we fix it with the most efficient solution proposed so far: http://bugs.python.org/file24143/random-2.patch

  2. Decide which versions of Python this should be applied to. 3.3 seems a given, the other are open to debate.

  3. If and only if (and I think this unlikely) the solution chosen is shown to be vulnerable to a more sophisticated attack then a new issue should be opened and dealt with separately.

Cheers, Mark.
