What utilities do you know for testing ssl?

Question

Nginx

There is a certain intranet service (application server) that uses https as a transport. It listens on port 443 and there is no access to it from the outside, only vpn. I configure nginx in terms of security and how can I check this whole thing?
nmap --script ssl-enum-ciphers -p 443 my.ipshows in principle the necessary ciphers.
Is there something similar , only "offline"?

Answer 1

man s_client
