SHA instruction set

Intel SHA Extensions are set of extensions to the x86 instruction set architecture which support hardware acceleration of Secure Hash Algorithm (SHA) family.

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 processors.
• Intel Ice Lake processors.

AMD

Several AMD processors support SHA instruction set:

• AMD Zen (and later) processors.
