note 20877 deleted from function.crypt by aidan

Note Submitter: karl@katzke.net ---- If you're importing DES encrypted passwords from a unix or linux environment, it seems that it is necessary to use the first to characters as a salt, especially if you're working off of an old implementation of unix (in my case, DYNIX). All that aside -- be aware of users that use apostrophes in their passwords. Although they're rare, they will break php's crypt function -- and I have not found a way around it, except to use an external function that isn't fazed by apostrophes. MySQL is a great example of this.
