> Do the other short names in /usr/include/openssl/obj_mac.h work? `tls ecdhe "X25519"` gives the OK to the configuration, but the site then fails to load in Chromium 58.0.3029.96 or Firefox 53.0.2, which should both have X25519 support.
`tls ecdhe "secp384r1"` gives the OK to the configuration, and the site loads fine in the above browsers, showing at least in Chromium curve "P-384" as the curve. I don't know if you can view the curve in use in Firefox. `tls ecdhe "auto"` gives the OK to the configuration, and the site loads fine in the above browsers, showing in Chromium curve "X25519" as the curve. Again, I don't know if Firefox shows the curve in use. `tls ecdhe "secp521r1"` gives the OK to the configuration, and the site loads fine in Firefox, but not Chromium (which does not support this curve). So, secp384r1 and secp521r1 seem to work as expected.
