Module password 

Secure passwords and tokens (Rails has_secure_password / has_secure_token).

Passwords are hashed with bcrypt; a model exposes its stored digest via HasSecurePassword to gain authenticate.

Traits

HasSecurePassword

Gives a model that stores a bcrypt digest an authenticate method.

Functions

generate_token

Generate an unguessable token (256 bits, hex) for has_secure_token and one-off tokens (password reset, etc.).

hash_password

Hash a password with bcrypt at the default cost.

hash_password_with_cost

Hash a password with an explicit bcrypt cost (higher = slower/safer).

verify_password

Verify a plaintext password against a bcrypt digest (false on any error).
