How to find certificates on the server that do not show up in MMC

I am in the process of upgrading SHA-1 certificates and some of the certificates do not show up in MMC. How can I find those certificates? Is there a way?

You might be using an application which does not use the Windows central store. Java applications for example often use a Java keystore in the application directory. Some applications load certs and cert chains directly from a config path. If the cert is in a Java keystore, look for the keystore. Look for a .jks. If the certs are just floating about in a directory then look for the certificate. Look for .cer, .crt, .pem for individual certs. Look for p7b for chains in a Windows format. If it loads the private key from the file then look for a .pfx extension.

Generally speaking the application documentation should tell you where the certs should be stored or how you can customise the cert location.

It seems you are looking at the wrong certificate store.

Check certificate stores for users, computers, and services.

The certificate owner told me they do not show up in MMC.  Do all the certificates show up there? What if certificate is simply copied into the application folder? How would I find it?

Is there a way I can retrieve all those using Powershell?
I don't know without more info. Talk to the cert owner for more info, it sounds like they should be able to elaborate on why it is not in the cert store. Maybe they know where?
