This policy setting determines the priority order of ECC curves used with ECDHE cipher suites.

- If you enable this policy setting, ECC curves are prioritized in the order specified.(Enter one Curve name per line)

- If you disable or don't configure this policy setting, the default ECC curve order is used.

Default Curve Order
 
curve25519
NistP256
NistP384

To See all the curves supported on the system, Use the following command:

CertUtil.exe -DisplayEccCurve.
