Jan 18, 2019 · Kudos to OpenVPN team for this. 1. Just like lzo, it should be clear that there isn’t much use to lz4 in place of lz4-v2 except for compatibility with older clients. Cipher algorithm and size. Different ciphers have different speeds in different hardwares (ie an AES-NI capable CPU). This is a hard topic to cover as it is up to you to decide
It is good that OpenSSL and OpenVPN can use AES-NI, but I was referring to that OpenVPN by default uses Blowfish and not AES, which is not supported by AES-NI if I am not mistaken. So in order to use the hardware engine one would have to manually change the config to use "cipher aes-128-cbc" or a similar supported cipher. I had been keeping my eyes open for a PC to become available that had a CPU with AES-NI support. I wanted to flash it with pfSense to see how OpenVPN performance compared with my Asus RT-AC88U. Eventually, I was able to obtain a Windows 7 PC with an Intel i5-3450 CPU @ 3.10GHz x 4 cores with AES-NI. AES-NI With the release of pfSense 2.4, OpenVPN 2.4.3 has been incorporated into pfSense. As a result, OpenVPN can use AES-NI acceleration for AES-GCM tunnels. AES-NI is a form of … - Selection from Mastering pfSense - Second Edition [Book] Aug 29, 2018 · Asus has had strong support for OpenVPN built into their routers for quite some time, and the ease-of-use of the stock AsusWRT is a nice-to-have feature. It was around $190 on Amazon at the time of this writing. It isn’t cheap, but it isn’t a bleeding edge $400 VPN router either. Testing OpenVPN on Private Internet Access: Considering the compatibility and versatility, this Netgate device is supportive towards IPsec, OpenVPN, IPV6, NAT, BGP, and many more formats. The device employs the Intel Atom CPU Quad Core 2.2 GHz which is providing you with utmost high performance and enhances the AES-NI performance effectively. In the interest of minimizing timing attacks on my OpenVPN and similar connections, does Raspberry Pi 4 support AES-NI instructions? Some reference to AES is made in the technical reference manual, but I don't see a conclusive answer anywhere.

Use a CPU with AES-NI when possible, and use AES-GCM for the Encryption Algorithm when possible. Note that for AEAD ciphers such as AES-GCM, OpenVPN ignores the setting for Auth Digest Algorithm . Note Mar 08, 2020 · The AES-NI is an extension to the x86 instruction set architecture for microprocessors from Intel and AMD. It increases the speed of apps performing encryption and decryption using the AES. Several server and laptop vendors have shipped BIOS configurations with the AES-NI extension disabled. Even though AES-NI is available, it does not mean you are going to use it. If you use the low level primitives like AES_*, then you will not use AES-NI because its a software implementation. If you use the high level EVP_* gear, then you will use AES-NI if its available. The library will switch to AES-NI automatically.

Hi, Thanks for your reply. I know that OpenVPN is single-threaded. But I expect more than 5MB/s on a CPU with 1,6/2,6 GHz and AES-NI support though. Consider that the OpenSSL speed benchmark showed that it's able to encrypt between 100 and 300 MB/s, even in the virtualized environment. Oct 03, 2018 · The second tweak made was to relink OpenVPN 2.1.4 using the OpenSSL 1.0.0a libraries with the Intel AES-NI patch applied. This patch is included by default in Fedora 12 and higher. Previously it was reported that the Intel AES-NI patch caused the performance on non-AES-NI capable hardware to improve by a factor of 2. OpenVPN¶ To take advantage of acceleration in OpenVPN, choose a supported cipher such as aes-128-cbc on each end of a given tunnel, then select BSD Cryptodev Engine for Hardware Crypto. Similarly, if the system employs the VIA Padlock engine, choose an appropriate cipher and select VIA Padlock for Hardware Crypto. It has AES-NI enabled as shown on the System Information "AES-NI CPU Crypto: Yes (active)". Also shows "Hardware Crypto: AES-CBC,AES-XTS,AES-GCM,AES-ICM". I have OpenVPN setup with "Hardware Crypto" under the OpenVPN server config set to "No Hardware Crypto Acceleration" as there is no other option. Sep 21, 2016 · Could someone remind me of the status of the H3 crypto engine, both hardware (capabilities, aes-ni ?) and software (mainline or vanilla kernels) ? I've been testing openvpn on an amlogic s905 box (still need to fix my beelink x2 problems) and as expected i'm hitting a cpu bottleneck. OpenSSL ＋ AES-NIパッチを使用する 次のチューンナップとして、OpenVPN 2.1.4とIntel AES-NIパッチ適用済のOpenSSL 1.0.0aをリンクさせてみます。このパッチはFedora 12以降にはデフォルトで組み込まれています。 Finally OpenVPN previously forked *after* initializing OpenSSL, which is arguably a bad choice. We'll fix the init order in OpenVPN. FreeBSD and/or OpenSSL should fix the weird default AES-NI/cryptodev behaviour, instead of asking all their users to work around it.
