Check systems trust store
I recently had to check whether a CA certificate was added to the trust store of a Linux I was working on. The system already had p11-kit installed so I could use the trust command like this: trust list This command lists all entries from the system's trust store. It's a quite long list but you can use grep to filter it and find exactly what you are looking for, like this: trust list | grep e-Szigno
