[Bug 987031] [NEW] archival hashes can be shortened

[Jeff Breidenbach]

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.
