About the Cryptographic Extension

The Cortex®‑A76AE core Cryptographic Extension supports the Arm®v8‑A Cryptographic Extension.

The Cryptographic Extension adds new A64, A32, and T32 instructions to Advanced SIMD that accelerate Advanced Encryption Standard (AES) encryption and decryption. It also adds instructions to implement the Secure Hash Algorithm (SHA) functions SHA-1, SHA-224, and SHA-256.


The optional Cryptographic Extension is not included in the base product. Arm supplies the Cryptographic Extension only under an additional license to the Cortex‑A76AE core and Advanced SIMD and floating-point support licenses.
