Migrating users from devise to bcrpyt-ruby

Hi guys,

How would one migrate users on a rails site using the devise gem for
authentication to using the bcrpyt-ruby gem(has_secure_password rails
option) for the same? I know that both use bcrpyt, but devise has the
stretches and pepper configurations in the devise.rb file and I’m a
uninformed on how to translate these for the bcrypt-ruby gem.

Is the pepper configuration in devise an active configuration when using
bcrypt or is that skipped. I know the stretches config is pretty
important(that’s the same as the workload right?). How would that

Any help will be greatly appreciated.

Thanks Guys,
