As a first step towards adding Object Integrity Proofs (FEP-8b32) to #Fedify, I've made it support #Ed25519 keys. I've also enabled multiple keys to be associated with an actor. For example, if you look at the actor from the Fedify Example Blog (https://fedify-blog.deno.dev/users/fedify-example), you'll see that it has two public keys, one for RSA and one for Ed25519.

You can try it out in version 0.10.0-dev.190+4dffb89a.

To all who are hosting their own #dns #authoritive server with #dnssec - what do you use in 2024?

#Ed25519 or #ECDSA-P256 or still on some #RSA algorithms? Shorter key length is especially in DNS a benefit but still not all resolvers may be able to support this in 2024?!

Thank you @Kovah for your detailed article. This shows what the current #SSH keys #security is. Now ALL of us just have to realize and implement this:

Ah ! Vu en retard : le ssh-keygen #OpenSSH 9.5 sorti début octobre génère désormais par défaut des clés #ed25519, en lieu et place de RSA

Today I learned that each time you derive an OpenSSH private key (say from an ed25519 private key), by design, you get a slightly different key (12 of the characters will be unique to each exported key even though the keys are equivalent to one another).

One of the last pieces of the puzzle for adding Ed25519 support to the WebCrypto API in Webkit now has a PR up.

So close.

Are you into #mathematics?
Do you know #students that still look for a subject to graduate on?

Assign them to implement #Ed25519 in #Erlang.

I was informed that the #Elixir community will thank you.

Would be great if the #AppSec community like #WeHackPurple and friends could spread the word!
