From what I gather from the internet (source), the recommended practice for 2019 and beyond is to avoid RSA and use ECDH and ECDSA.

Is this the general case?

  • $\begingroup$ @AleksanderRas blog.cloudflare.com/how-expensive-is-crypto-anyway would be one example. RSA is still alive, just in minority use. And I wonder whether its usage will continue to dwindle. $\endgroup$ – Bastien Feb 8 at 10:23
  • $\begingroup$ From what I can gather by just quickly reading the article is that the RSA although secure is apparently not as efficient as other asymmetric systems (ECDH & ECDSA) that have around the same security, therefore more and more people will leave RSA and change to a more efficient algorithm. I don't have the actual knowledge for efficiency of different algorithms though... $\endgroup$ – AleksanderRas Feb 8 at 13:15
