.get_password_hash(password, salt, algorithm = nil) ⇒ Object

Method gets a password hash with or without salt using supplied hashing algorithm. :sha512 is used if an algorithm is not supplied

Parameters:

  • password (String) —

    Password to hash

  • salt (String) —

    Salt for enforcing password protection security. Use nil if you want to hash password without salt

  • algorithm (:symbol) (defaults to: nil) —

    Hashing algorithm. May be one of followings: :sha1, :sha256, :sha512.

def self.get_password_hash(password, salt, algorithm = nil)
    data = password
    data = salt + data if salt && !salt.blank?
    self.hash_it(data, algorithm)
end

.hash_it(data, algorithm = nil) ⇒ Object

Method gets a hash using supplied hashing algorithm. :sha512 is used if an algorithm is not supplied

Parameters:

  • data (String) —

    Data to hash

  • algorithm (:symbol) (defaults to: nil) —

    Hashing algorithm: :sha1, :sha256, :sha512.
