It's a really nice anecdote where I see myself reflected haha, I'm just in the middle of something similar with RSA and Ed25519, and also the post-quantum cryptography scene.
But usually once I'm done investigating and I think I understood something well enough I simply bookmark the links, write some bullet points in my notes and that's it.
Do you also have this issue? Do you finish the investigation and start writing for a blog post right away? Or do you just come back to it after some time?
Haha this is exactly me.
That habit of losing the knowledge rapidly post investigation is something I'm trying to break, and that's part of the reason I banged out this blog post immediately after my itch was satisfied.
The "I have to tell people about this NOW" vibe also carried me through completing my website (just so I could publish this blog post)
Out of curiosity are ye planning to do a post about RSA and ED25519?
I do want to, not sure when, but I'll find the time since OP gave me a bit of a boost in confidence I can do it :)
I'll be sure to read it when you do :)
That is really interesting. Does anyone have an example of what a web finger might contain? It says avatar data but I’m interested in how sites use it.
Hey
Thanks for reading, and I'm glad you found it interesting.
To my understanding, Webfinger provides a standard API for discovering the user profile details no matter the software running on the node.
lol well look at that. that's neat. seems a bit roundabout. How do you know the resource though? so you request the user information with the resource query param, but that means you already know the user, which means you likely got it from somewhere else right? if you got it from somewhere else, you likely have the ability to get the profile information from that location rather than requesting information twice. or am I thinking about this completely wrong?
for example, I completely understand the chatgpt plugin and change password ones, but this one doesn't really make sense to me, since you have to know information before hitting it.
You are right that it does feel a little roundabout. My understanding is that webfinger converts from the username to the user profile url and image. This is useful during federation, and for generic fedi/activitypub clients because different Fedi software maps usernames and profiles differently.
For example, user@lemmy.instance will reside at lemmy.instance/u/user, while user @mastodon.instance will reside at mastodon.instance/user.
Fom some poking around, it seems that Lemmy does not properly support sending the profile image on Webfinger because I wasn't able to do it using the rel parameters that are mentioned in the spec.
Love these little compsci investigation articles. Thanks for sharing!
Glad you liked it! Thanks for reading ❤️
