Simple Encryption and Decryption Workflow

This n8n workflow provides a straightforward solution for encrypting and decrypting data. It's designed to be triggered by another workflow, accepting an action type ('encrypt' or 'decrypt'), a secret key, and the data to be processed. The workflow intelligently routes the request to either the encryption or decryption node based on the provided action type. The encryption process uses a XOR cipher with a given key, then encodes the result in Base64. The decryption reverses this process, taking Base64 encoded input, decoding it, and then applying the XOR cipher with the same key to retrieve the original data. This makes it ideal for scenarios where sensitive information needs to be protected during transit or storage.
