Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

n8n Node: WhatsApp Media Decrypt

NPM Version License Downloads

Read in English


Português 🇧🇷

[cite_start]Este é um nó customizado para a plataforma n8n que descriptografa arquivos de mídia do WhatsApp[cite: 28].

Muitas integrações com a API do WhatsApp fornecem apenas a URL direta para o arquivo de mídia e uma mediaKey para descriptografá-lo. Este nó automatiza o processo de download, descriptografia e disponibilização do arquivo para ser usado em outras etapas do seu fluxo de trabalho.

Instalação

Para instalar este nó em sua instância n8n:

  1. Vá para Settings > Community Nodes.
  2. Selecione Install.
  3. Digite n8n-nodes-whatsapp-decrypt e clique em Install.

Após a instalação, o nó "WhatsApp Media Decrypt" aparecerá na lista de nós para ser adicionado ao seu workflow.

Como Usar

O nó precisa das seguintes informações de entrada para funcionar:

  • [cite_start]URL do Arquivo: O link direto para o arquivo de mídia criptografado, geralmente começando com https://mmg.whatsapp.net/...[cite: 3].
  • [cite_start]Media Key: A chave de descriptografia (mediaKey) correspondente ao arquivo, em formato Base64[cite: 3].
  • [cite_start]Tipo do Arquivo (Extensão): A extensão do arquivo que você está tentando descriptografar (ex: jpg, mp4, pdf)[cite: 3]. Isso é crucial para que o algoritmo de descriptografia funcione corretamente.
  • [cite_start]Nome do Arquivo de Saída: O nome que você deseja dar ao arquivo final, sem a extensão[cite: 4, 5].

O nó irá processar esses dados e retornar um arquivo binário na saída, que pode ser usado por outros nós (por exemplo, para enviar por e-mail, salvar no Google Drive, ou processar com uma IA).

Compatibilidade de Arquivos

[cite_start]O nó suporta uma vasta gama de tipos de arquivo, incluindo[cite: 3, 4]:

  • [cite_start]Imagens: JPG, JPEG, PNG, WEBP [cite: 4]
  • [cite_start]Vídeos: GIF, MP4, 3GP, MOV [cite: 4]
  • [cite_start]Áudios: MP3, OGG, AAC, Opus [cite: 4]
  • [cite_start]Documentos: PDF, DOCX, XLSX, PPTX, TXT, ZIP [cite: 4]

[cite_start]This is a custom node for the n8n platform that decrypts WhatsApp media files[cite: 28].

Many WhatsApp API integrations only provide a direct URL to the media file and a mediaKey to decrypt it. This node automates the process of downloading, decrypting, and making the file available for use in other steps of your workflow.

Installation

To install this node in your n8n instance:

  1. Go to Settings > Community Nodes.

How to Use

The node requires the following input information to work:

  • [cite_start]File URL: The direct link to the encrypted media file, usually starting with https://mmg.whatsapp.net/...[cite: 3].
  • [cite_start]Media Key: The corresponding decryption key (mediaKey) for the file, in Base64 format[cite: 3].
  • [cite_start]File Type (Extension): The extension of the file you are trying to decrypt (e.g., jpg, mp4, pdf)[cite: 3]. This is crucial for the decryption algorithm to work correctly.
  • [cite_start]Output File Name: The name you want to give the final file, without the extension[cite: 4, 5].

The node will process this data and return a binary file in the output, which can be used by other nodes (e.g., to send via email, save to Google Drive, or process with an AI).
