OpenSSH's `ssh-keygen` command just got a great upgrade.In today's episode, I cover how Ed25519 keys are now the default, and how it probably doesn't impact ...

    Isn’t elliptic curves cryptography sensitive to quantum computers attack? Shor’s algorithm etc

      Yes, it is. ed25519 depends upon discrete log for its security, which Shor’s algorithm can (theoretically, of course, not like it’s ever been done) efficiently solve.

      The post-quantum algorithms are in active research right now. I don’t blame anyone for avoiding those at least until we’ve quantum computers big enough to solve baby toy elliptic curves.

      I had to create one this year after discovering that connectbot (ssh client on Android) didn’t support agent forwarding otherwise.

        Probably a good idea to look for a different client, call me tinfoil but I wouldn’t want to touch a very old mechanism that is supported/pushed by a very recognisable 3 letter agency

          I’ve just started using SSH inside of Termux, got tired of all the weird pitfalls SSH Clients for Android usually have

          Probably. It’s in f-droid but increasingly looking not quite unmaintained, but not developed actively enough.
