node-red-contrib-whatsapp-media-decrypt 0.0.2
a NodeRed node to decrypt whatsapp media
NodeRed Whatsapp Media Decrypt module
project inspired by node-red-contrib-whatsapp-link, while imageMessage is received from the node, still would want to get the image for further processing.
This project is used to decrypt whatsapp encrypted media file "file.enc" download from url.
To Use
put the image message in msg.message.imageMessage
as follow.
{
"url": "url of the file.enc file, <https://mmg.whatsapp.net/o1/...>",
"mimetype": "image/jpeg",
"fileLength": "1234567",
"fileEncSha256": "hash of encrypted file in base64",
"mediaKey": "decryption key"
}
If the object is straight coming from node-red-contrib-whatsapp-link, it should all be available
Result is stored at msg.imageMessageBuffer as Buffer
If you chain it with node-red-contrib-image-tools, you should be able to check the picture in viewer node.
TODO
- to support more types of media, such as video type etc...
