Ruby on Rails gem to make passwords more secure? -

-

i built ruby on rails authentication system scratch , works great.

(i aware of existence of devise, yet wanted write own system better grasp of ruby on rails in general.)

the thing worries me users pick words dictionaries, sequential numbers (e.g. "12345679"), own user names, or all-time classic "password" own password.

is there gem validates against of those? or have work regular expressions here?

thanks help.

stong_password gem cool. though may not contain looking for, still pretty gem
