If you have a pfx file you will need to decrypt it (unless you are on the latest version on MSL)
If the file was named wildcard certificate the instructions would be something like the below
You will need the password to decrypt the pfx file. This was created the same time as the certificate
When installing the certificate you will need three files
the key.pem , cert.pem and the intermediate cert.
You get the intermediate file from the certificate provider. If godaddy.com then you can find them here
You need to run these commands on the msl server logged on as root.
If you have never used putty to ssh on to the msl before you can look at my how to post here
openssl pkcs12 -in “Wildcard Certificate.pfx” -out certificate.cer -nodes
openssl pkcs12 -in “Wildcard Certificate.pfx” -nocerts -out key.pem -nodes
openssl pkcs12 -in “Wildcard Certificate.pfx” -nokeys -out cert.pem
openssl rsa -in key.pem -out server.key
