Here is the entire section of code :
def self.authenticate(login, password)
    user = find_by_login(login)
    return user if user && user.authenticated?(password)
  end

  def authenticated?(password)
    hashed_password == encrypt(password)
  end

  protected
   def encrypt_new_password
     return if password.blank?
     self.hashed_password = encrypt(password)
   end

   def password_required?
     hashed_password.blank? || !password.blank?
   end

   def encrypt(string)
     Digest::SHA1.hexdigest(string)
   end
