If you are impacted by an expired root CA certificate, you have two options: 1) re-install the certificate or 2) get a new certificate from a different CA.

Generate SSH Keys in PEM Format to Connect to a Public or On-Premises sFTP Server Verify the key by opening the file in Notepad. The key must start with the following phrase.Use -m PEM with ssh-keygen to generate private keys in PEM format: Copy ssh-keygen -t rsa -m PEM.

Procedure Take the file you exported (e.g. certname.Run the following command to export the private key: openssl pkcs12 -in certname.pfx -nocerts -out key.pem -nodes. Run the following command to export the certificate: openssl pkcs12 -in certname.pfx -nokeys -out cert.pem.
