Replace Certificates - PFX File

[TSprouse94]

Looking to replace the self signed certificates in my VCSA 6.7 appliance.  My security team provided me with a .pfx file which I copied over to a temp directory on my VCSA appliance.   I am now not 100% sure what openssl commands to run to extract the appropriate files needed to replace the self signed certificates.

Any smart openssl people out there that can lend some guidance.

You need to get them to give you a base64-encoded certificate in PEM format.

So imported the PFX file into vCenter in a temp directory and ran these three commands:

openssl pkcs12 -in <filename.pfx> -nocerts -nodes | sed -ne '/-BEGIN PRIVATE KEY-/,/-END PRIVATE KEY-/p' > <clientcert.key>
openssl pkcs12 -in <filename.pfx> -clcerts -nokeys | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > <clientcert.cer>
openssl pkcs12 -in <filename.pfx> -cacerts -nokeys -chain | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > <cacerts.cer>

That gave me the three files I was looking for and replaced the certificates with no issue.

Hi TSprouse,

I had generated the three files from pfx. How to proceed further? Can you say where I have to replace these files?
