Can you reverse bcrypt?

Can you brute force bcrypt?

1 Answer. Bcrypt use a configurable iteration count, so the answer to your question is: whatever you want it to be. If the iteration count is such that one bcrypt invocation is as expensive as 10 computations of MD5, then brute-forcing the password will be 10 times more expensive with bcrypt than with MD5.

"`bcrypt` forces you to follow security best practices as it requires a salt as part of the hashing process. Hashing combined with salts protects you against rainbow table attacks!

Is bcrypt broken?

Bcrypt is an algorithm that makes cracking these passwords almost an impossible task – it was thought the process to crack the 15 million leaked Ashley Madison passwords would take decades. Instead, almost all of them were broken in less than two weeks.
