log_rounds config doesn't seem to make a difference

[pdilyard]

I've added the log_rounds config option to my test config file to speed up the tests, but no matter what value I put it doesn't seem to make a difference.

config/config.test.exs:

# Speed up our test suite
config :comeonin, :bcrypt_log_rounds, 4

I tried bumping the number up to 200 to see if it was taking effect, and the tests ran in exactly the same time. I also added the configuration to config/config.exs to be 100% sure it was being loaded, and got the same results.

Try changing it to 14 or 16. That should make a big difference.
200 won't work because the maximum number of log_rounds is 31 (and the minimum is 4).
To truly verify that it's working or not, check the hashes that are produced - they should start with "$2b$" and then the next two numbers will tell you the number of log_rounds.

Yep that worked, thanks!

The important part is that you create a new user or change the password on the user after you've implemented the changes whenever you change this in order to see any difference.
