I worry that people will experiment with the new feature using your example, and then we'll get bug tickets because the resulting keystore doesn't work with TLS.

This is exactly the advice I need from an expert.

However, secp384r1 is already the default choice for `-keysize 384`. Do you have another recommendation that has to be set with `-groupname`?

Thanks
