# Crackeo con Cowpatty contra una tabla arcoíris
Usa Cowpatty con una base de datos GenPMK precomputada y un handshake capturado.
Después de crear una base de datos GenPMK, Cowpatty puede usarla para verificar un handshake capturado.
La base de datos y la captura deben usar el mismo nombre de red. Aquí, el ESSID es `jordan`.
### Ejecute la búsqueda
Use el `dic.genpmk` base de datos con la captura:
{% code overflow="wrap" %}
```bash
cowpatty -d dic.genpmk -r Capture-01.cap -s jordan
```
{% endcode %}
Los parámetros son:
* `-d dic.genpmk` selecciona la base de datos GenPMK.
* `-r Capture-01.cap` proporciona el handshake capturado.
* `-s jordan` establece el nombre de la red objetivo.
Cowpatty encuentra la contraseña en menos de 0.03 segundos. La tasa de búsqueda es de 445,106 contraseñas por segundo.
Los valores precalculados hacen que la búsqueda sea mucho más rápida. Evitan recalcular cada candidato durante este paso.

## 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/es/hacking-wifi/wpa-wpa2-psk-network-attacks/precomputed-attacks/cowpatty-cracking-against-a-rainbow-table.md?ask=&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.
