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 introduced in 2013.
There are seven new SSE-based instructions, four supporting SHA-1 and three for SHA-256:
SHA1RNDS4,SHA1NEXTE,SHA1MSG1,SHA1MSG2SHA256RNDS2,SHA256MSG1,SHA256MSG2
x86 architecture processors[]
Intel[]
The following Intel processors support SHA instruction set:
- Intel Goldmont (and later Atom microarchitectures) processors.[1]
- Intel Ice Lake (and later) processors.[2]
- Intel Rocket Lake (and later) processors.
AMD[]
Several AMD processors support SHA instruction set:
- AMD Zen (and later) processors.[3]
