Intel SHA extensions

Intel SHA Extensions are 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, SHA1MSG2
  • SHA256RNDS2, 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 processors[2].

AMD

Several AMD processors support SHA instruction set:

  • AMD Zen (and later) processors[3].
gollark: The glass you transfer milk to is NOT superfluous.
gollark: Yes, that's right, good inference.
gollark: Oh, <@734160436194181170>?
gollark: Rounded to the nearest 2021, it is 2080.
gollark: Interesting presumption.
