OpenSSL - Padding Oracle in AES-NI CBC MAC Check. CVE-2016-2107 . dos exploit for Multiple platform Mar 17, 2014 · OpenSSL’s openssl command can do many tasks. It can be used to measure performance via openssl speed. By default, openssl (which builds with an AES_ASM option) will automatically use Intel AES-NI HW acceleration. It also provides a simple way to disable HW acceleration via setting one environment variable: OPENSSL_ia32cap to ~0x200000200000000 The source code, as well as a bunch of general-purpose benchmarks for it, are available in my AesNi repository. This AES implementation lets us use the round keys calculated as described in the second post directly, getting rid of all the framework overhead. To encrypt or decrypt, all round keys are loaded into 128-bit (XMM) registers. Installs Win32 OpenSSL v1.1.1g (Only install this if you need 32-bit OpenSSL for Windows. Note that this is a default build of OpenSSL and is subject to local and state laws. More information can be found in the legal agreement of the installation. Win64 OpenSSL v1.0.2u Light: 3MB Installer In OpenSSL code, the AESNI_CAPABLE macro does the job (feeding on some flags which are set when the library is initialized, using CPUID). Bottom-line: with EVP, you benefit from the automatic selection of the improved implementation, based on the current CPU model, whereas the non-EVP code directly uses the generic software implementation As of OpenSSL 1.1.1, providing subjectAltName directly on command line becomes much easier, with the introduction of the -addext flag to openssl req (via this commit).. The commit adds an example to the openssl req man page:

How can I check if OpenSSL is support/use the Intel AES-NI

kldunload aesni kldload cryptodev. openssl speed -evp aes-256-cbc. note output. then. kldload aesni openssl speed -evp aes-256-cbc. if you compare outputs from all tuns you will see which combination of modules works for you (note that openvpn utilise openssl) in my case the faster aes operations i am getting when aesni and cryptodev are laoded.

OpenSSL on Oracle Solaris 11.2 | Oracle Solaris Blog Thanks for the question. Inlined AES-NI instruction is available in Solaris 11.2 OpenSSL libraries. `truss -lf -u libcrypto:: -o /tmp/truss.out openssl speed -evp aes-128-ctr` will show the use of aesni instructions. Unfortunately, for ssh/sshd, if the cipher used is the AES CTR mode, there is a special code in Solaris ssh/sshd which prevents the inlined AES-NI instruction from being used. RE: Error building OpenSSL-1.1.1g Note that using masm to compile OpenSSL is no longer supported by us (although it might still work). Preferred is to use the VC-WIN64A target and the nasm compiler. If you use the Developer Studio command prompt (64-bit) it should have all the environment variables … Cryptographic Module Validation Program | CSRC The OpenSSL FIPS Object Module 2.0 is a general purpose cryptographic module delivered as open source code. It is designed for ease of use with the popular OpenSSL cryptographic library and toolkit and is available for use without charge for a wide variety of platforms.
