Public bug reported: The draft for archival hashes for mailman specifies 32 character, base 32 encoding. We can get away with 13 characters which expects the first collision at around 50 billion messages. The the wikipedia charts in their "birthday attack" article. It's not like an occasional collision is a big deal and this is not a security issue. ** Affects: mailman Importance: Undecided Status: New ** Tags: mailman3 ** Tags added: mailman3 -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/987031 Title: archival hashes can be shortened To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/987031/+subscriptions
