Support mTLS auth for feed

[timofurrer]

• I have read this document: https://miniflux.app/opinionated.html#feature-request

Miniflux already support HTTP basic auth for feeds. Would it be possible to additionally support mTLS auth?

I may actually be willing yo contribute it myself if it's something you would support :)

I never seen any feeds using mTLS so far. Is it for some internal systems? do you have any examples?

[timofurrer]

Yes, it's for an internal system ... I'm also producing personal RSS feeds and currently use basic auth but would like to switch to mTLS.

I don't have an example that you could use. However, you could just put an RSS fees behind a Caddy mTLS client auth.

[fguillot]

That would require people to provide the client cert, private key, and optionally the CA cert for a given feed.

I may actually be willing yo contribute it myself if it's something you would support
