FAQ

Why add client auth for onion service?

When you have an onion service for private use, adding client auth makes it completely secure against DDOS even when the service's URL is leaked. Even if you don't explicitly share the onion address, it can leak via HTTP Referrer or Origin headers or accidental copy paste.

Why this tool?

The official way requires to install packages and run multiple long shell command lines. This is a zero dependency pure go mini tool that is quick and easy to use.
