Re: OpenSSH Password Question
From: "Bluefish (P.Magnusson)" <11a () GMX NET>

Assume you use strong passwords with a-zA-Z0-9 and 8 characters long
passwords. You get 36^8 possible different passwords, [...]
a-zA-Z0-9 is 62, no? So it'd be 62^8?

Yep, must have been asleep while typing. The assumption was based on
a-z0-9 or something. And yes, you are right on crypt() being 64 bits.

Silly me! :)

Anyway, looked at the bcrypt papers pointers were refering to? If the
scheme is considered to be safe by cryptographers, it's one pretty neat
idea, adding a factor of 2^cost [where cost is an variable] to the time
complexity of the algorithm.
