Performance Comparison of AES and SM4 Encryption Algorithms Using OpenVPN: National Secret Algorithm Doesn't Seem So Bad

From the previous test (Performance Comparison of Different Encryption Algorithms in OpenVPN), we found that there are differences in forwarding performance when OpenVPN uses different encryption algorithms, as shown below: Comparing the encryption algorithms, we can see that the specific encryption algorithms are divided into three parts: the first part is the algorithm name, which … Read more

Performance Comparison of Different Encryption Algorithms in OpenVPN

We previously introduced that the forwarding performance of IPsec VPN varies with different encryption algorithms (using vSRX to test the performance differences of various IPsec VPN encryption algorithms), but does OpenVPN have this issue? First, we need to confirm the algorithm information used during the OpenVPN negotiation process. For the default configuration, the algorithm information … Read more
