user = User.find_by_email('test2@endpoint.com')
actual_password = "password"

# compare digest and user.crypted_password here to verify password
Note that the stretches value for Authlogic defaults to 20, but it can be adjusted. Also note that Authlogic uses the SHA-512 hash function by default.
For password, it adds ‘password_hash’ and ‘password_salt’ columns, to store those encrypted values.
