Not all attackers are created equally.
I still see this a simple matter of violating KISS to introduce a layer of encryption. The question is, to which end? Sure, an attacker might see the encrypted file and think it's "too difficult" for him to get to the passwords. Another might use a certain utility to decrypt the said file. The thing is, to which end are we encrypting the data? Just for the sake of making it work like the N other programs? I mean, if this doesn't *work*, why even *bother*?
There is no question here. There is no discussion. It should be done, and if it is not, password saving should be stopped in FileZilla or an alternative program should be sought. It's that simple.
Great. If it's so simple that it can be done in under 10 mins, go complain to them. As to "go read our awesome security standards we created", that is the exact reason why I consider this "security feature" completely useless. Cheers, Chris.

Given that this is open source, security through obscurity can't even start working (-> encrypting local files with a local key / using custom algo == security through obscurity).No, you are completely wrong and I encourage you to specifically consider a layered threat model or perhaps just read the information *already presented* in this thread. Not all attackers are created equally. There is no question here. There is no discussion. It should be done, and if it is not, password saving should be stopped in FileZilla or an alternative program should be sought. It's that simple. (Note that BeyondCompare and probably at least N other programs out there *do* perform a trivial encoding of the passwords, and it is a good and appropriate policy).Chris.-- silky http://dnoondt.wordpress.com/ "Every morning when I wake up, I experience an exquisite joy — the joy of being this signature."
