Note Submitter: benjamin dot morel at gmail dot com ---- The comment by nickshanks is totally uninformed, you can trust the documentation that explicitly says that the length will always be 60 chars. The cost is exponential, and its current range (as per crypt() documentation) is 04-31. Reaching 100 would require our computers to be 590295810358705651712 times faster. Reaching 1000 would require our computers to be 5e291 times faster (that's 5 followed by 291 zeros).
