how long does it take to crack a salted sha1 password based on the hash alone

gistfile1.txt

assume the salt and password are comprised of 62 characters: a-zA-Z0-9

assume a 40 char salt

so the hashed string for a 6 letter password is 46 chars

62^46 = 2*10^82 permutations

at 700,000,000 passwords tried per second, you'd need 4*10^73 seconds to try all permutations

that's 1*10^66 years.

Newer GPU-based methods can do ~2,300,000,000 SHA1 checks per second. http://www.golubev.com/hashgpu.htm

Still good enough, of course ;-).
