Hi @Anexon, I am not sure what exactly this 3rd party npm module does, so I won’t be able to compare it with the n8n Crypto node unfortunately.
Do you have any documentation for the API your arecalling? Perhaps you can use the default Node.js crypto module instead of the crypto-js? In the Code node you could simply require it using const crypto = require('crypto'); (this works out of the box on cloud, on self-hosted n8n instances you might need to allow it first as described here for example).
