Modifying a Certificate Authority signed certificate import file
You can add a Certificate Authority signed certificate without generating a certificate signing request in the Control Center. If you have not exported the certificate from a Symantec Messaging Gateway appliance, you must first modify the certificate import file.
To modify the certificate import file, remove the passphrase from the key used to generate the certificate signing request. Next, combine first the certificate and then the modified key into a new file. Save the combined file locally, and import it into the Control Center to add it to the list of available certificates. The certificate must be in PEM format.
To modify a Certificate Authority signed certificate import file
Delete the passphrase from the key used to generate the certificate signing request.
You can use the following command:
# openssl rsa -in key.pem -out key-nopass.pem
where key.pem is the input filename of the key, and key-nopass.pem is the output filename for the key without the passphrase.
Create a new text file.
Copy the certificate into the new file.
Below the certificate, copy the public key without passphrase into the new file.
