Intel SHA extensions
Intel SHA Extensions are a set of extensions to the x86 instruction set architecture which support hardware acceleration of Secure Hash Algorithm (SHA) family. It was specified in 2013.[1] Instructions for SHA-512 was introduced in Arrow Lake and Lunar Lake in 2024.
The original SSE-based extensions added four instructions supporting SHA-1 and three for SHA-256.
- SHA-1:
SHA1RNDS4,SHA1NEXTE,SHA1MSG1,SHA1MSG2 - SHA-256:
SHA256RNDS2,SHA256MSG1,SHA256MSG2
The newer SHA-512 instruction set comprises AVX-based versions of the original SHA instruction set marked with a V prefix and these three new AVX-based instructions for SHA-512:
VSHA512RNDS2,VSHA512MSG1,VSHA512MSG2
x86 architecture processors

[edit]All recent AMD processors support the original SHA instruction set:
Intel
[edit]The following Intel processors support the original SHA instruction set:
- Intel Goldmont[3] (2016) and later Atom microarchitecture processors.
- Intel Cannon Lake[4] (2018/2019), Ice Lake[5] (2019) and later processors for laptops ("mainstream mobile").
- Intel Rocket Lake (2021) and later processors for desktop computers.
The following Intel processors will support the newer SHA-512 instruction set:
- Intel Arrow Lake and Lunar Lake processors.
