Intel SHA Extensions are set of extensions to the x86 instruction set architecture which support hardware acceleration of Secure Hash Algorithm (SHA) family. Introduced on Intel Goldmont microarchitecture. AMD added support in their processors for these instructions starting with Ryzen.
There are seven new SSE-based instructions, four supporting SHA-1 and three for SHA-256:
