# Craquage Pyrit contre une table arc-en-ciel

Utiliser Pyrit avec une base de données GenPMK pour vérifier un handshake WPA/WPA2 capturé.

Le `dic.genpmk` la base de données peut également être utilisée avec Pyrit.

Pyrit utilise `attack_cowpatty` pour vérifier les valeurs pré-calculées par rapport à la poignée de main capturée. L’ESSID doit correspondre à celui utilisé lors de la création de la base de données.

### Exécutez la recherche

Utilisez la base de données, la capture et le nom du réseau :

{% code overflow="wrap" %}

```bash
pyrit -e jordan -i dic.genpmk -r Capture-01.cap attack_cowpatty
```

{% endcode %}

Les paramètres sont :

* `-e jordan` définit le nom du réseau cible.
* `-i dic.genpmk` importe la base de données pré-calculée.
* `-r Capture-01.cap` fournit la poignée de main capturée.

Pyrit trouve le mot de passe immédiatement. Il vérifie environ 2 millions de mots de passe par seconde.

La base de données pré-calculée évite de recalculer chaque candidat lors de la recherche.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://hacking-notes.jord4n.pro/fr/hacking-wifi/wpa-wpa2-psk-network-attacks/precomputed-attacks/pyrit-cracking-against-a-rainbow-table.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
