是否有任何的x86指令来加速SHA(SHA1 / 2 /五百一十二分之二百五十六)编码? [英] Are there in x86 any instructions to accelerate SHA (SHA1/2/256/512) encoding?
问题描述
一个例子,在 86的指令集,硬件加速AES 。但在有任何的x86指令来加速SHA(SHA1 / 2 /五百一十二分之二百五十六)编码,什么库编码在x86 SHA的fastet?
An example, in x86 are Instruction Set to hardware acceleration AES. But are there in x86 any instructions to accelerate SHA (SHA1/2/256/512) encoding, and what library is the fastet to encoding SHA on x86?
推荐答案
在英特尔 SKYLAKE微架构微到达2015年,公认的答案将是不正确时,它说:英特尔并没有作出专门的指令集的SHA-1或两个。 英特尔upcomming说明加速SHA1 / 256哈希计算。
Once the Intel Skylake microarchitecture arrives in 2015, the accepted answer will be incorrect when it says: "Intel hasn't made dedicated instruction set for SHA-1 or two". Intel has upcomming instructions for accelerating the calculation of SHA1/256 hashes.
