So, RSA is deprecated now

[tomlopez4676]

But what's the replacement for SSH? I've found a few posts from people trying to use Elliptic Curve/ECDSA, but no-one seems to have it working. It doesn't seem to be supported.

Are we supposed to keep using RSA until something better comes along, despite being deprecated?

Is there something else out there that I've missed?
