alt Hacker NewsI’m talking specifically about RSA being eventually broken. If just RSA is broken and you were using ECDHE for symmetric keying, then you’re fine.
The point is that you can build stuff on top of RSA today even if you expect it to be broken eventually if RSA is only for identity verification.
The relevant RSA break is sufficiently powerful quantum computers, which also break ECDH (actually, ECDH is easier than classically equivalent-strength RSA for quantum computers[1]), so no, you’re not fine.
