May 13, 2016 · These tests were executed with several changing variables, such as AES-NI enabled and AES-NI disabled. As shown in Figure 3, OpenSSL version 1.0.2f performed at 786 MB/s 8192 bytes block size when AES-NI is enabled. MacBook-Pro:bin $ ./openssl speed -elapsed -evp aes-128-cbc You have chosen to measure elapsed time instead of user CPU time.
Apr 28, 2016 · Quoting form the draft of OpenSSL upstream advisory: Padding oracle in AES-NI CBC MAC check (CVE-2016-2107) ===== Severity: High A MITM attacker can use a padding oracle attack to decrypt traffic when the connection uses an AES CBC cipher and the server support AES-NI. AES-NI is also supported on Open Servers. Affected encryption algorithms include: AES-CBC (128-bit and 256-bit) AES-GCM (128-bit and 256-bit), which shows the most significant improvement - with AES-NI, it is faster than AES-CBC, when both sides support AES-NI. Without AES-NI support, it is slightly slower than AES-CBC + HMAC-SHA1 Oct 03, 2018 · 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. Closer investigation showed that the system OpenSSL library 0.9.8e-fips is actually at fault: after recompiling OpenSSL from source, with or without the Intel AES-NI patch, the performance also doubled. Solaris AESNI OpenSSL Engine for Intel Westmere. Cryptography is a major component of secure e-commerce. Since cryptography is compute intensive and adds a significant load to applications, such as SSL web servers (https), crypto performance is an important factor. openssl speed -evp aes-128-cbc. OpenSSL 1.1.1c 28 May 2019. type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes 16384 bytes. aes-128-cbc 62939.79k 76141.21k 82262.20k 84452.51k 83872.20k 85103.02k. openssl speed -evp aes-256-cbc. OpenSSL 1.1.1c 28 May 2019 It's dual CPU's supported AES-NI, so when decided to separate my firewall/gateway/etc.. off my ESXi server (mostly so that I didn't bring down the internet every time I needed to tinker/reboot) I wanted a CPU with AES-NI (which for Intel Gen 3 meant at least an I5).
Dec 05, 2014 · Using Intel AES-NI on Android. The OpenSSL library’s AES algorithms show significant performance gains over those provided by the native Java Provider. This is because the library is optimized for Intel processors and makes use of the AES-NI instructions. Below is a step-by-step description of how to encrypt a file using OpenSSL provider.
The rngd daemon, which is a part of the rng-tools package, is capable of using both environmental noise and hardware random number generators for extracting entropy. The daemon checks whether the data supplied by the source of randomness is sufficiently random and then stores it in the kernel's random-number entropy pool.
Sep 07, 2011 · The built-in version had AES-NI support compiled into it, and I compiled a version that didn’t include the hooks. The command I ran was openssl speed -evp aes-128-cbc. The trick is that the software must be told to use the AES-NI instruction set. You can check to see if OpenSSL has AES-NI support built-in by running the command openssl engine.
Subject: How can I enable aes-ni in openssl on Linux I recently became aware of aes-ni and found the linked articles. My CPU supports this, but it seems (assuming the advice in the linked pages is accurate) that openssl does not have it enabled.
