# Creación de una tabla arcoíris con GenPMK
Genera una base de datos de claves WPA/WPA2 precomputadas con GenPMK.
GenPMK crea una base de datos PMK precalculada a partir de una lista de contraseñas y un nombre de red.
Cada contraseña genera una clave para un ESSID específico. Generar estos valores de antemano acelera las búsquedas posteriores.
### Consulta la herramienta
{% code overflow="wrap" %}
```bash
genpmk
```
{% endcode %}
### Generar la base de datos
Usa la lista de contraseñas y el ESSID para crear la `dic.genpmk` base de datos:
{% code overflow="wrap" %}
```bash
genpmk -f passwords.txt -s jordan -d dic.genpmk
```
{% endcode %}
Los parámetros son:
* `-f passwords.txt` importa los candidatos de contraseña.
* `-s jordan` establece el nombre de la red objetivo.
* `-d dic.genpmk` define la base de datos de salida.
La base de datos generada puede reutilizarse para el mismo ESSID. Evita volver a calcular las mismas claves.

## 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/creating-a-rainbow-table-with-genpmk.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.
