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. Why Intel® AES-NI Matters. Encryption is frequently recommended as the best way to secure business-critical data, and AES is the most widely used standard when protecting network traffic, personal data, and corporate IT infrastructures. 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. Re: How to enable AES-NI Post by mikedpitt » Mon Mar 28, 2016 3:54 pm Looking at OpenSSL.org's page, it seems their latest supported LTS version is 1.0.2. A flaw in the OpenSSL handling of CBC ciphersuites in TLS 1.1 and TLS 1.2 on AES-NI supporting platforms can be exploited in a DoS attack. Reported by Adam Langley and Wolfgang Ettlinger. Fixed in OpenSSL 1.0.1d (Affected 1.0.1-1.0.1c) CVE-2013-0169 (OpenSSL advisory) 04 February 2013:
May 04, 2016 · On May 3, 2016, the OpenSSL Software Foundation released a security advisory that included six vulnerabilities. Of the six vulnerabilities disclosed, four of them may cause memory corruption or excessive memory usage, one could allow a padding oracle attack to decrypt traffic when the connection uses an AES CBC cipher and the server supports AES-NI, and, lastly, one is specific to a product

Aug 22, 2019 · The tests for each input data size was performed for 3 seconds, for the ciphers that we were interested in. Five modes with 128-bits key, AES-NI enabled and disabled, encryption(the first row means OpenSSL will use ase-ecb with 128-bits key to encrypted 1371968.28k data in 3 seconds):
A flaw in the OpenSSL handling of CBC ciphersuites in TLS 1.1 and TLS 1.2 on AES-NI supporting platforms can be exploited in a DoS attack. Reported by Adam Langley and Wolfgang Ettlinger. Fixed in OpenSSL 1.0.1d (Affected 1.0.1-1.0.1c) CVE-2013-0169 (OpenSSL advisory) 04 February 2013: openssl RaspberryPi PINE64 AES-NI. More than 3 years have passed since last update. Pine64+到着 1.3 Older Distributions: Applying AES-NI Patch to OpenSSL The OpenSSL libraries distributed with older versions Linux, such as RHEL5, do not support Intel AES-NI. To add this capability the patch should be downloaded from openssl.org , apply the patch to OpenSSL and then recompile the Apache Web server. You can verify that OpenSSL uses Intel AES-NI by running OpenSSL's internal benchmarks. Compare the output of openssl speed aes-128-cbc with openssl speed -evp aes-128-cbc . The former skips hardware acceleration even if present, while the latter uses acceleration if available. OpenSSL AES-NI Padding Oracle MitM Information Disclosure Low Nessus Plugin ID 91572.
