Show HN: Website for creating self-signed certificates

If you’re developing locally and need to use HTTPS for whatever, then this tool is hopefully useful to you.

I made it because there’s a lot of bad info online about generating self-signed certificates. For instance, a lot of guides don’t use the SAN list extension or show you how to create a proper certificate chain. Firefox doesn’t allow a CA certificate to be used as an end certificate. Getting a working certificate can get pretty confusing, especially for newcomers to certificates or webdev.

Having a website for this also means the process of getting a certificate is the same, no matter if you’re on a Unix-like OS or Windows.

A WebAssembly module built with C++ and Mbed TLS is used to create the keys and certificates. TypeScript and Preact is used for the UI.
