Re: Jabber support

Nope, you can send a message to persons that have filled in a Jabber ID in their profile. Integrating Jabber with the private messages would be reeeeeeally cool but that's fairly difficult at the moment. Well, actually it's pretty simple but it requires the use of a bot or polling a Jabber server. R...

Re: Code improvement in session.php (phpbb 2.2)

BTW it would be even more efficient to switch the order of the two queries. Only two fields are fetched from the sessions table, the users table is quite a bit bigger which would save on the foreach loop.

Re: Password hashing function

And don't forget that you shouldn't be running it on a shared server which is where 99% of the phpBB forums end up :)

Re: Password hashing function

True, but from what I got from all of this is that a collision attack is quite a bit different (mathematically) from a preimage attack. And of course, in 50 years you'll probably be able to crack an MD5 hash in 2 split seconds, but should we worry about that? :D Changing from MD5 to something else i...

Re: Password hashing function

Ok, I see where you're going but this is way too far fetched for me :D Ok, I've read the article and if I understand it correctly they need to know the IV to create a second IV that produces the same hash. So you need to know the password to find a string that produces the same MD5 hash. Not very us...

Re: Password hashing function

Eeeh, I really don't seen what all this fuss is about, if you have access to the hash, why would you want to waste time on finding a collision?

Re: Can 2.0.x upgrade to 2.2.x smoothly?

Of course there will be a smooth upgrade path from 2.0 to 2.2 My board has approx 5M posts at the moment and the database (including indices) is approx 5.5GB This will have to be converted to 2.2 and, yes, that will take more than 30 seconds :D
