If your database is stolen, the thief won't have your users' plaintext passwords, only the hashes.

So, the thief won't be able to try to use that password in another system (as many users use the same password everywhere, this would be dangerous).

## Install `passlib`

PassLib is a great Python package to handle password hashes.

It supports many secure hashing algorithms and utilities to work with them.

* Konfigurieren Sie alle erforderlichen Berechtigungen und Rollen mithilfe von Abhängigkeiten.
* Speichern Sie niemals Klartext-Passwörter, sondern nur Passwort-Hashes.
* Implementieren und verwenden Sie gängige kryptografische Tools wie Passlib und JWT-Tokens, usw.
* Fügen Sie bei Bedarf detailliertere Berechtigungskontrollen mit OAuth2-Scopes hinzu.
* ... usw.

repository for all Gradle builds. Gradle will check hashes (md5 and sha256) of used dependencies and will fail builds with
`Dependency verification failed` errors when local artifacts are absent or have different hashes listed in the
[verification-metadata.xml](https://github.com/JetBrains/kotlin/blob/master/gradle/verification-metadata.xml) file.

    Und mit allen gleichzeitig kompatibel sein.

Erstellen Sie eine Hilfsfunktion, um ein vom Benutzer stammendes Passwort zu hashen.

Und eine weitere, um zu überprüfen, ob ein empfangenes Passwort mit dem gespeicherten Hash übereinstimmt.

Und noch eine, um einen Benutzer zu authentifizieren und zurückzugeben.
