Last week, I tried to register for a service and was really surprised by a password limit of 16 characters. Why on earth yould you impose such strict limits? Never heard of correct horse battery staple?

A major US bank that I used to use has case insensitive passwords, found that out one day when I noticed caps lock was on after logging in with no trouble

Makes you wonder if they store the password in plain text, or convert to lower key during your first input so it's at least hashed. I wouldn't be surprised if it's not.

they store the passwords as filenames on a windows system

Put a colon in your password and crash the whole system

set your password as GodMode.{ED7BA470-8E54-465E-825C-99712043E01C} for infinite money glitch

I don't think it could be hashed if it is case insensitive. It's fairly early so I may be misremembering but I'm not aware of any hashing algo that ignores case.

Edit: Ah, actually they could be storing the password as a hash, but they would probably have to do like a password. ToLower() call or something where they morphed the string before checking... The thought of which just makes me shudder.

Early 2000s internet banking was a trip.

i think this was about a year ago when they changed it....

The fact that it was a power of 2 makes me suspect lazy coding. That bank didn't pay its programmers well enough.

Banks don't have much money for paying people, methinks. They're famously poor practically non-profits.

[–] lseif@sopuli.xyz 1 points 11 months ago

maybe they store the entire password as a u64 and bitmask out each character

I had to make a 10 character password for Santander

[–] proton_lynx@lemmy.world 3 points 11 months ago (2 children)

No no, not 8 characters, 8 numerical characters!

[–] JackbyDev@programming.dev 6 points 11 months ago (1 children)

Whoa whoa whoa, did you use two of the same number in a row? Insecure!

[–] proton_lynx@lemmy.world 2 points 11 months ago

Is that a sequence? No way, José!

[–] milicent_bystandr@lemm.ee 3 points 11 months ago

Numerical Chateaubriand*, and total sum must be less than 3.

* okay Google, if that's what you really think I meant to type.

Ha. I had the same thing, with a government-run student loan website
