I mistook this for being about usernames at this hacker forum

Passwords should be hashed client-side anyway, so the real issue there is how to encode the password hash in a way that satisfies the legacy system. But this is usually plausible, e.g. by base64 or hex encoding the hash to avoid disallowed characters and then appending specific characters that satisfy the set of required characters.

Do you know of any systems that actually do this? It's the first I've heard of this technique.

Nothing should be doing this. Insecure legacy systems that wrongfully expect to see the plaintext of the user's password should be replaced with properly functioning ones. But just because they haven't been yet is no excuse to actually give them the plaintext of the user's password.

I've sent feedback to a couple dozen sites over this. Most were government website (internal military sites are the worst) but when various financial institutions started updating their policies they forcing this silliness. When they don't allow spaces in passwords either, I worry.

Keep in mind, there are situations where the website you're using is interfacing to backend systems that have constraints that can't easily be changed (colloquially known as "legacy systems"). Feedback is good, but change takes time.

I'm somehow supposed to care that it's the vendor's tech debt that makes them insecure, instead of regular old bad practices?

Yeah this is annoying. Simply consider a^b, what makes that expression grow faster, increasing a, or increasing b? b is better mathematically and for mental overhead.

The mathematical part was not obvious to me, so:

The derivative with respect to a is: b(a^(b-1)).

The derivative with respect to b is: log(a)(a^b) or (a log(a))(a^(b-1)).

So it's better to increase b when alog(a) > b. Which is typically the case where a is 26 for lowercased letters and b is like 10 for password length.

This analysis might not be totally correct since the cost of adding one extra allowed character vs increasing password length by one is not the same but w/e.

TreasuryDirect is pretty bad about this -- the passwords are not case-sensitive, and they need to be entered using an on-screen keyboard.

A quicker fix for a brand new forum would be to not use some janky old PHP codebase.

dchuk has put their money where their mouth is and have made their own decisions wrt platform as is their right. Put up or shutup.

Thanks!

The banner should be about 10% of its current height.

To be fair, it's only really big on the homepage, all other pages it gets much smaller.

And there I think it should be 90% smaller too
