Could be potentially nice for fediverse server testing, as more implementations make the jump to final RFC 9421 HTTP signatures.

On the flip side, ever more complex curl invocations (here: Accept header plus signature fields plus key file, presumably) suggest use of more specialized CLI tools, such as provided by @fedify, or at least scripts/aliases.

Speaking of RFC 9421, which notable fediverse implementations can't handle it yet? Anyone keeping track?

@julian @fedify I’m honestly not aware of any that do support it yet…

@hazelnoot @fedify At the very least, Mastodon and Fedify (and by extension Hollo and Ghost) do. Outside of those I'm very unsure! I've seen @silverpill talk about it a bunch, so maybe Mitra supports it as well.

@julian @hazelnoot @fedify Mitra can verify RFC-9421 sigs.

I think all FEP-844e implementations support RFC-9421 in some capacity. The list of known implementations includes:

- Streams / Forte
- ActivityPub for WordPress
- tootik

@[email protected] how do I test against Mitra?

@julian Just send a request with RFC-9421 signature. It should return 401 on failure.

Mitra doesn't use RFC-9421 for signing outgoing requests.
