Intel SHA extensions

● Article ● Talk ● Language ● Watch ● Edit

Intel SHA Extensions are a set of extensions to the x86 instruction set architecture which support hardware accelerationofSecure Hash Algorithm (SHA) family. It was introduced in 2013. Instructions for SHA-512 will be 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. AVX-based versions are also available with a V prefix.

SHA-1: SHA1RNDS4, SHA1NEXTE, SHA1MSG1, SHA1MSG2
SHA-256: SHA256RNDS2, SHA256MSG1, SHA256MSG2

The AVX-based extensions added three for SHA-512.

VSHA512RNDS2, VSHA512MSG1, VSHA512MSG2

The following Intel processors support the original SHA instruction set:

Intel Goldmont (and later Atom microarchitectures) processors.^[1]
Intel Ice Lake (and later) processors.^[2]
Intel Rocket Lake (and later) processors.

The following Intel processors will support the newer SHA-512 instruction set:

Intel Arrow Lake and Lunar Lake processors.
