The rui.pfx file is a concatenation of the system’s certificate and private key, exported in the PFX format. The file is copied to the subdirectory on the vCenter Server system.

Personal Information Exchange Format (PFX) enables transfer of certificates and their private keys from one computer to another or to removable media. The Microsoft Windows CryptoAPI uses the PFX format, also known as PKCS #12.

Export the certificate and key file together to PFX format using OpenSSL.

openssl pkcs12 -export -in rui.crt -inkey rui.key -name rui -passout pass:testpassword -out rui.pfx


You must use the password testpassword.
