I’m interested mainly listing all the valid values for SSL_CTX_set1_group_list().  I see the man page for that function has a list of valid groups/curves for TLS 1.3, but also mentions providers can change that list, and does not give a list for valid curves in other TLS versions.

The only command I know is ecparams for listing all included curves:

$ openssl ecparam -list_curves

This gives a comprehensive list. Is this what you needed?
