SimpleHIBP

SimpleHIBP is a very simple way to check your password safety against Troy Hunt's Have I Been Pwned range password API.

Usage

As the idea of this is to keep it simple, you'll just need to call isPasswordSafe() static method, passing it the password you want to test as the only argument, and get a boolean value as the return:

• true if the submited password hasn't been seen in a leak
• false if has been seen

Example

use HIBP\SimpleHIBP;

$password = "someth1ng";
if (SimpleHIBP::isPasswordSafe($password)) {
  echo "My password is safe :)";
} else {
  echo "My password is unsafe :(";
}

Security

• It's obvious, but your data (password, hashed password) are never stored
• So, there is no cache at all (see Limitation)

Limitation

To keep it simple, there is no caching at all. If you plan to integrate it on a high loaded website, please add some form of caching. Something like that should do the job (for security reason, I highly recommend you not to use the password as a data for the cache key):

use HIBP\SimpleHIBP;

$password = "someth1ng";
$key = "someUniqueUserData";
if (false === ($result = $cache->get($key))) {
  $result = SimpleHIBP::isPasswordSafe($password);
  $cache->set($key, $result);
}
