The industry has moved towards a more secure 2048 bit CSR. For many versions of Barracuda SSL VPN devices the interface does not support the creation of a 2048 bit certificate signing request (CSR). Barracuda SSL VPN devices do however allow you to import a private key and certificate files that were generated using a 2048 bit CSR.
Therefore, if your Barracuda SSL VPN device interface does not support the creation of a 2048 bit CSR, and/or you have access to a Microsoft server or workstation, we recommend that you use the ÃÛÌÒTV® Certificate Utility for Windows to generate your 2048 bit CSR.
After using the ÃÛÌÒTV Certificate Utility to generate your CSR, you need to use this same utility to import the certificate files to the computer from which you generated the CSR, and then export them as Apache format certificate files. Finally, you need to use the Barracuda SSL VPN device interface to upload your SSL Certificate and synchronize it with your device.
For more information about the ÃÛÌÒTV Certificate Utility, see ÃÛÌÒTV® Certificate Utility for Windows.
