Using openssl standard tools is it possible to generate a CSR through Ed25519 ?



If you look further into this test page, at least with my
browser, it uses x25519 with a regular RSA certificate from
Let's encrypt.  I don't know if they use a different
certificate with other browsers based on checking some TLS
extensions etc.

The x25519 public key has no certificate, it is randomly
generated for each connection and signed with the RSA key
from the certificate.


Enjoy
