How to check if a user requires SSL in Mysql?

Question

I'am testing with an AWS RDS Mysql instance with Mysql verison 5.7.22.

After requiring ssl for a specific user, 'root' (GRANT USAGE ON . TO 'root'@'%' REQUIRE SSL;"), this is the result of SHOW GRANTS for root;

+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| Grants for root@%                                                                                                                                                                                                                                                                                                              |

Is there anyway I can check to see that ssl is required for a user? Show grants output doesn't mention ssl. I would think that Show grants is the right command to use because ssl was initially required on the user via GRANT USAGE.

Answer 1

One thing I found was that from the client, you can run status to determine if the current connection is using ssl. Not sure if there's a way to do it for a specific user though.

Edit

Chris White's solution(MySQL: REQUIRE SSL not shown in grants) works for a specific user
