I still use Twofish on a pool of pseudo-random entropic fun to generate long ASCII filled passphrases with alphanumeric characters, punctuation and such. Most sites today behave properly, but it still trips up a few.
ERROR: Passwords may not contain the character “\”.
Too long: Use at most 50 characters
Password must be less than 50 characters long.
Dashzen… doesn’t show anything.
But the winner is the NSW OneGov site:
The characters Spaces, @, ‘, ?, +, : are not allowed
There may be some data sanitising going on here, or an attempt to reduce support queries from people forgetting increasingly longer passphrases. Still, there’s absolutely no technical reason why a site in 2014 can’t salt and hash exactly what you give it.
