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. > > -- > Stephen Wall The only command I know is ecparams for listing all included curves: $ openssl ecparam -list_curves This gives a comprehensive list.
