<shamelesly edited copy from wikipedia> Assume a user's secret key is stolen and he is known to use one of 200,000 English words as his password. The system uses a 8-bit salt. The amount of combinations is 256*200000 = 51200000. </shamelesly copy from wikipedia> If attacker chacks one hash per second and has 64-core beowulf cluster it will require 9 days to check all possible combinations. That's not so much, imo. Also, processors are cheap these days one guy [1] has build 96-core machine (for unknown price).
