Feasibility of Upgrading Cryptography?

[Librechain]

Your use case

Was tempted to add this in as an 'issue', but recently the NSA deprecated 256-bit strength cryptography (secp256k1 specifically; I think the NIST SP reference still recommends ed25519).

In either case, was wondering about the feasibility of upgrading to ed448. otrv4 has a similar scheme to megolm, and the increase in overhead is negligible. Minus ed448, there are no additions to any of the libraries that I can think of at this point.

Not Demanding the Change

If I can implement it on my end personally, I'm happy to do so. Just wondering if there are any caveats or things I should look out for first.

Thank you in advance for taking time to answer this.

Have you considered any alternatives?

Only alternative would be using XMPP; I already have that integration in tow - but for other things.
