## Passwort-Hashing

„Hashing“ bedeutet: Konvertieren eines Inhalts (in diesem Fall eines Passworts) in eine Folge von Bytes (ein schlichter String), die wie Kauderwelsch aussieht.

Immer wenn Sie genau den gleichen Inhalt (genau das gleiche Passwort) übergeben, erhalten Sie genau den gleichen Kauderwelsch.

Sie können jedoch nicht vom Kauderwelsch zurück zum Passwort konvertieren.

# Let dex keep a list of passwords which can be used to login to dex.
enablePasswordDB: true

# A static list of passwords to login the end user. By identifying here, dex
# won't look in its underlying storage for passwords.
#
# If this option isn't chosen users may be added through the gRPC API.
staticPasswords:
  - email: "******@****.***"
    # bcrypt hash of the string "password"

* Das **hereinkommende Modell** sollte ein Passwort haben können.
* Das **herausgehende Modell** sollte kein Passwort haben.
* Das **Datenbankmodell** sollte wahrscheinlich ein <abbr title='Ein aus scheinbar zufälligen Zeichen bestehender „Fingerabdruck“ eines Textes. Der Inhalt des Textes kann nicht eingesehen werden.'>gehashtes</abbr> Passwort haben.

### Visit <http://localhost:8080>

You will be redirected to dex login screen - click "Login with email", enter username password
> username: ******@****.***
> password: password

and then click "Grant access"

On the browser now you shall see the list of buckets output, along with your temporary credentials obtained from MinIO.

* The **output model** should not have a password.
* The **database model** would probably need to have a hashed password.

Never store user's plaintext passwords. Always store a "secure hash" that you can then verify.

If you don't know, you will learn what a "password hash" is in the [security chapters](security/simple-oauth2.md#password-hashing){.internal-link target=_blank}.
