Add this line to your application's Gemfile:

gem 'password_hasher'

And then execute:

$ bundle

Or install it yourself as:

$ gem install password_hasher

password = "goodpass"
hashed_password = PasswordHasher.hash_password(password)
#hashed_password == something like "sha1:1000:9NYDQj80ksetV+0uW/6VAJwXKTGDqKyv:SnRzqabSk/Kpmb9C109NIv+zbHArz4kg"
validated = PasswordHasher.validate_password(password, hashed_password)
#validated == true

PasswordHasher will automatically add salt and the number of iterations and return those values in the string.
