To use the Laravel NIST Password Rules in your project, first use the PasswordRules class, then call the appropriate static methods to return an array of appropriate validation rules. There are methods available for the following scenerios.

• Register
• Change password, with old password
• Change password, without old password
• Optionally change password, with old password
• Optionally change password, without old password
• Login

See the code below for example usage syntax.

use LangleyFoxall\LaravelNISTPasswordRules\PasswordRules;

// Register
$this->validate($request, [
    'email' => 'required',
    'password' => PasswordRules::register($request->email),
]);

// Register, without requiring password confirmation
$this->validate($request, [
    'email' => 'required',
    'password' => PasswordRules::register($request->email, false),
]);

// Change password, with old password
$this->validate($request, [
    'old_password' => 'required',
    'password' => PasswordRules::changePassword($request->email, 'old_password'),
]);

// Change password, without old password
$this->validate($request, [
    'password' => PasswordRules::changePassword($request->email),
]);

// Optionally change password, with old password
$this->validate($request, [
    'old_password' => 'required',
    'password' => PasswordRules::optionallyChangePassword($request->email, 'old_password'),
]);

// Optionally change password, without old password
$this->validate($request, [
    'password' => PasswordRules::optionallyChangePassword($request->email),
]);

// Login
$this->validate($request, [
    'email' => 'required',
    'password' => PasswordRules::login(),
]);

The optionallyChangePassword method supplies validation rules that are appropriate for forms in which the password can be optionally changed if filled in.
