WARNING

This module is not a replacement for two factor authentication.

Users are actively locked out if their password is found to be pwnd and forced to reset their password.

Although it adds to the user security te enforce unique passwords, this module will not prevent any password leaks like the ones used by HaveIBeenPwned.

Have I Been Pwned for SilverStripe

This module checks on password change and login, if the SHA1 of the password appears in the Have I Been Pwnd database.

There is never a full password transmitted to HaveIBeenPwned, only the first 5 characters of a SHA1 of the password, the response from HaveIBeenPwned is then compared locally.

Given the nature of HaveIBeenPwned, even if a password is intercepted (the connection is HTTPS and Troy Hunt is not the easiest when it comes to security), the password has already been out in the wild, so this scenario is a very unlikely one to cause more breaches.

Only a count of the amount of times the password shows in the database is collected, next to which known breaches contain the users Email or Username. This information about the password and the email are unrelated. HaveIBeenPwned does not provide a relation between the two. On purpose.

SilverStripe Framework 4.x GuzzleHttp 6.x PHP 5.6+

Applying the validator extension to other PasswordValidators

Add the following to either of your config yml files. (Suggested is using an extensions.yml file)

MyVendor\MyNameSpace\MyPasswordValidator:
  extensions:
    - Firesphere\HaveIBeenPwned\Extensions\PasswordValidatorExtension

Replacing the vendor\namespace\validator with your own Validator namespace and classname

By default, if the default PasswordValidator isn't registered, this module will register it to make sure the changes are applied. You can override this in your own _config.php file.

Only environment

To not make engineers life impossible and allow for using pwnd passwords on local environments in dev mode, by default, the Pwnd service is turned off in dev mode

Can I USe

Simply put? Sure. Admitted, this is Open Source software, and in theory, you can use it any way you want.

You can license this work, by buying a usage subscription. It will allow you to request support, or just supporting the developer.

But it is licensed BSD!

Yes, it is and you can use it as such. I'd just appreciate a bit of help every now and then.
