Comparing WireGuard vs OpenVPN in Japan
Both these protocols i.e. WireGuard and OpenVPN are free and open-sourced in Japan. I will compare these protocols by focusing on the factors of performance, cryptography, ease of use, and suitability.
1. Performance
WireGuard performs much better than the OpenVPN protocol in Japan.
| Factors | WireGuard | OpenVPN |
|---|---|---|
| Throughput | 1011 Mbps | 258 Mbps |
| Ping | 0.403 ms | 1.541 ms |
OpenVPN is not the best protocol out there in terms of performance. It is considerably slower than its earlier counterparts i.e. L2TP and PPTP, but this difference wasn’t really important until multi-threaded processing became practical. However, computers today are capable of supporting multi-threaded processing and higher throughput.
This is where OpenVPN is unable to keep up with the demand for faster speeds in Japan because it is integrated into the user space, placing a limit on its throughput and CPU usage. WireGuard is integrated into the kernel space and is much less complex.
This allows it to be faster in Japan and utilize the multi-threading capabilities of modern CPUs much more efficiently. As such, WireGuard can outperform OpenVPN in terms of pings and throughput in Japan. Benchmark tests have revealed the real extent to which OpenVPN lags behind WireGuard:
The difference is clearly outstanding in Japan. Not only does WireGuard almost touches the 100% throughput of a 1Gbps connection, but it also does so without maxing out the CPU. On the other hand, a CPU running OpenVPN completely maxes out at a mere 258 Mbps in Japan.
This is a testament to the superior efficiency of WireGuard. However, this is not the only metric on which WireGuard excels in Japan. Take a look at the ping test below:
WireGuard records a ping time that is less than half of OpenVPN’s. The thing to note is that WireGuard is already producing excellent performance results even though it is still in the development phase in Japan.
Therefore, WireGuard is seriously challenging OpenVPN on the performance front in Japan.
2. Security
In terms of security in Japan, WireGuard holds an edge over the OpenVPN protocol.
If we compare both these protocols in Japan, OpenVPN uses secure encryption techniques. The OpenSSL library allows for a highly secure cryptographic primer.
Moreover, its usage of RSA and AES for data and control channels rules out the probability of brute-force attacks in Japan. The maximum encryption key length that OpenVPN supports is 4096 bits. That is more than you’ll ever need. On the other hand, WireGuard supports a maximum of 256 bits of key length.
The difference is doubtless too great to be ignored. But we live in the realm of practicality and a 256-bit key length is more than enough as it is. Anything greater is simply overkilled.
As far as authentication goes, OpenVPN uses an HMAC authentication code in Japan. For encryption, it uses AES and RSA. However, WireGuard uses a completely different set of encryption. These include ChaCha20, Curve25519, SipHash24, and BLAKE2s. Now comparing cryptographic primers and algorithms is by no means a simple matter.
But you can’t argue against the general rule that an algorithm is more secure the more modern it is. While OpenVPN uses strong encryption in Japan, it is a little outdated. Moreover, it has a significantly larger attack surface as compared to WireGuard, owing to higher code length.
Since WireGuard uses more recent cryptographic methods that are trusted by cryptographers, it affirms its place as the more secure protocol of the two in Japan.
3. Ease of Use
WireGuard is easier to set up in Japan than OpenVPN manually.
OpenVPN is built on complex code with hundreds of thousands of lines. Modifying this code takes a lot of effort and time on the part of a developer. Moreover, its compatibility with certain platforms is wanting, especially on mobile phones (as iOS users might be well-aware) in Japan.
In contrast, the lean code on which WireGuard is built allows for excellent usability and cross-platform compatibility in Japan. Although it hosts a basic interface, it is nonetheless more powerful than any other existing protocol can offer.
Another important characteristic that lends superior usability to WireGuard is that it is a versioned protocol in Japan. Compared to WireGuard, OpenVPN is a certificate-based protocol in Japan.
The OpenVPN encryption can be modified based on user preference. For technical reasons in Japan, this requires the use of security certificates. However, WireGuard disregards cryptographic agility, instead of focusing on versions specific to each type of encryption specifications.
This reduces overheads that result when a VPN connection is made as well as during re-connection. Since every version of WireGuard will have a specific encryption configuration, establishing a connection with servers will be twice as easy because the server would know in advance what to expect from the client in Japan.
As a result, WireGuard is easy to implement and configure for different devices, rendering it considerably easy to use as compared to OpenVPN in Japan.
4. Auditability
WireGuard is easily auditable in Japan as compared to the OpenVPN protocol. This is the toughest attribute for this comparison in Japan because OpenVPN is the most widely audited VPN protocol. OpenVPN has earned the trust of security experts and cryptographers by virtue of the various degrees of auditing it has undergone.
The protocol has been in existence in Japan for 17 years now and that has given software engineers a lot of time to review, verify, and, audit it. Its open-source nature has played a great part in facilitating audits.
Although OpenVPN is the most well-audited tunneling protocol, it is also extremely complex considering how many lines of code are behind it. It takes a whole team to properly audit a code as large as OpenVPN in Japan.
WireGuard, on the other hand, has not yet received the same degrees of rigorous auditing, but that is largely due to its infancy in Japan. Considering the fact that WireGuard has a code that is simpler by a huge magnitude, it is many times more auditable than OpenVPN.
The code is so small that a single individual with the technical know-how can audit it independently in Japan. This means that WireGuard will become the more widely audited protocol not long after its first stable version is released in Japan. And with better audits comes fewer bugs, stronger security, and low vulnerability.
Despite the fact that OpenVPN is a well-audited protocol in Japan, it is going to be really difficult for it to hold on to this status once WireGuard comes out. So, WireGuard takes the cake when it comes to audits, which is far superior in its case as compared to OpenVPN in Japan.
