# Criando uma Tabela Rainbow com GenPMK
Gere um banco de dados de chaves WPA/WPA2 pré-computadas com GenPMK.
GenPMK cria um banco de dados PMK pré-calculado a partir de uma lista de senhas e do nome da rede.
Cada senha gera uma chave para um ESSID específico. Gerar esses valores antecipadamente acelera as buscas posteriores.
### Confira a ferramenta
{% code overflow="wrap" %}
```bash
genpmk
```
{% endcode %}
### Gere o banco de dados
Use a lista de senhas e o ESSID para criar o `dic.genpmk` banco de dados:
{% code overflow="wrap" %}
```bash
genpmk -f passwords.txt -s jordan -d dic.genpmk
```
{% endcode %}
Os parâmetros são:
* `-f passwords.txt` importa os candidatos a senha.
* `-s jordan` define o nome da rede de destino.
* `-d dic.genpmk` define o banco de dados de saída.
O banco de dados gerado pode ser reutilizado para o mesmo ESSID. Ele evita calcular as mesmas chaves novamente.

## 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/pt-br/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.
