Hi, I cannot import certificate from CA (Certificate Authority). When I attempt to install the certificate to CSACS SE 4.2, the following error occurs during installation: "Unsupported private key file format".
There are 2 ways to install a certificate on an ACS appliance, the easiest one is generating a CSR (Certificate Sign in Request) from the ACS, copy the CSR format into your CA and then retreiving the Certificate from your CA and upload it via FTP to your ACS SE, this is easiest since the Private key that you define is generated by ACS SE and saved into it's System and into an FTP server with the correct format (PEM)
The other way, hardest, is generating the Certificate from the CA and exporting it to a PKCS12 format in which you will have the Identity Certificate and the Private key wrapped on a PFX file, then since ACS SE does not support this you will need to manage and process this with OPENSSL to change the encoding from Base64 to PEM and then extracting both the Certificate file and the Private key file which then you can import using an FTP server.
