Subject Re: CouchDB, require_valid_user and brute force

Hi Martin,

If you mean some kind of rate-limiting for authentication requests, no (though that's a neat
idea). The next release of couchdb brings PBKDF2 as an enhancement to the SHA1 passwords hashes.
This brings a configurable work factor which effectively limits the rate of authentication
(at a cpu cost). It would be simple to impose a fixed and configurable delay to authenticating
on top of that, though.
