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.
