XOR Encryption & Decryption with Base64 for n8n Workflow Data

This n8n workflow enables basic XOR encryption and decryption of text data, combined with Base64 encoding for safe transmission. It processes input as an array of JSON objects specifying 'action-type' (encrypt or decrypt), 'key' (password), and 'data' (content). Using JavaScript Function nodes, it applies bitwise XOR operations with the key repeated to match data length, then Base64-encodes for encryption output or decodes and XORs for decryption.

Key benefits include quick data masking within n8n ecosystems without external services, seamless integration as a sub-workflow, and no dependencies. It's lightweight, executing in milliseconds, and returns structured results matching input format for easy chaining.

Ideal use cases: obfuscating internal messages, API payloads, or config values between workflows; testing encryption logic; temporary data hiding in automations. Not suitable for production security due to XOR's vulnerabilities like known-plaintext attacks—use only for non-sensitive data.

Deploy by calling via Execute Workflow node, providing example inputs like encrypt 'Hello' with key 'Password' yielding Base64 output, or reverse for plaintext recovery.
