I have a cert expiring on 2/20/20 in the Virtual Host Certificate Management page. The team who create certs gave me the new ones, but I have no idea how to add or activate them. I have read the help pages within RSA but they make no sense to me, since I know nothing about certificates. Any information or help will be appreciated.
If the CA cert team gave you a file with *.cer or *.p7b extension, that's PKCS#7 format and does not need a password. You would have generated the Cert Signing Request, CSR in the AM Operations Console ...,
...and the private key from the PKI key pair would only be in the AM Web Tier Key store. That's why there's no password on the *.cer or *.p7b file. You CA Cert team would have signed your CSR request file.
If the CA cert team gave you a file with *.pfx or*.p12 extension, that is PKCS#12 format, it needs a password because the CSR was generated somewhere else, with another tool, and therefore the private key is in the .pfx or.p12 file
