Figure 5 Example of a Certificate Request
You have generated a base 64 encoded PKCS#10 file (Public Key Certificate Syntax-10), which most CAs recognize or require. The system automatically saves this file in Flash memory with the filename shown in the browser (pkcsNNNN.txt).
In generating the request, the system also generates the private key used in the PKI process. That key remains on the VPN Concentrator in encrypted form.
