Frequently Asked Questions
Which algorithms are supported?
This version supports HS256 and none, which cover most local debugging and test integration scenarios.
Do you store my JWT secret?
No. Secrets and payloads are processed client-side and are never sent to a backend service.
Can I use generated tokens in production?
Use caution. This tool is primarily for development and testing; production signing should run in secure backend infrastructure.
