Right, this was what I was seeing/thinking about: >>> for i in range(41): print i, "'" + "password"[:i-40] + "'" ... 0 '' 1 '' 2 '' 3 '' 4 '' 5 '' 6 '' 7 '' 8 '' 9 '' 10 '' 11 '' 12 '' 13 '' 14 '' 15 '' 16 '' 17 '' 18 '' 19 '' 20 '' 21 '' 22 '' 23 '' 24 '' 25 '' 26 '' 27 '' 28 '' 29 '' 30 '' 31 '' 32 '' 33 'p' 34 'pa' 35 'pas' 36 'pass' 37 'passw' 38 'passwo' 39 'passwor' 40 '' Can't really call it wrap around, I guess. > > > Might make debugging a problem just a little > > easier, you never know. > > > > Anyway: > > > > def checkPassword(self, storedPassword, password): > > salt = storedPassword[:max(0, len(storedPassword)-40)] > > return storedPassword == self.encodePassword(password, salt) > > With Python you can do things as simply as possible. :-) The > expression > storedPassword[:-40] (which is equivalent to > storedPassword[:len(storedPassword)-40]) does exactly what you want: > > >>> "password"[:-40] > '' > Keeping it simple is often the best way. Given the above, in order to ensure a blank salt with a password less than 40 characters, keeping it simple may not suffice.
