Back-of-the-envelope crack time estimations, in seconds, based on a few scenarios

Fields

online_throttling_100_per_hour: u64

Online attack on a service that rate-limits password attempts

online_no_throttling_10_per_second: u64

Online attack on a service that doesn't rate-limit, or where an attacker has outsmarted rate-limiting.

offline_slow_hashing_1e4_per_second: u64

Offline attack, assumes multiple attackers. Proper user-unique salting, and a slow hash function such as bcrypt, scrypt, PBKDF2.

offline_fast_hashing_1e10_per_second: u64

Offline attack with user-unique salting but a fast hash function such as SHA-1, SHA-256, or MD5. A wide range of reasonable numbers anywhere from one billion to one trillion guesses per second, depending on number of cores and machines, ballparking at 10 billion per second.
