ISAL(4) Kernel Interfaces Manual ISAL(4) NAME isal -- driver for AES acceleration on x86 CPUs SYNOPSIS To load the driver as a module at boot time, place the following line in loader.conf(5): isal_load="YES" DESCRIPTION This driver provides an interface between the Intel Intelligent Storage Ac- celeration Crypto Library and the kernel opencrypto framework. The library provides optimized routines that implement encryption and decryption for various modes of the AES cipher and computations of secure hashes. These optimized routines use the AESNI instructions as well as various vector in- struction extensions including SSE4.1, AVX, and AVX2. This driver currently supports the following algorithms: Algorithm Required CPU Extensions AES-GCM-128 AESNI and SSE4.1 AES-GCM-256 AESNI and SSE4.1 isal provides support for fewer algorithms than aesni(4). However, it will provide improved performance for supported algorithms compared to aesni(4). SEE ALSO aesni(4), crypto(4), intro(4) FreeBSD ports 15.quarterly May 28, 2021 ISAL(4)
