Module: Clearance::PasswordStrategies::BCrypt

Defined in:
lib/clearance/password_strategies/bcrypt.rb

Overview

Uses BCrypt to authenticate users and store encrypted passwords.

The BCrypt cost (the measure of how many key expansion iterations BCrypt will perform) is automatically set to the minimum allowed value when Rails is operating in the test environment and the default cost in all other envionments. This provides a speed boost in tests.
