About

The vector crypto extensions allow accelerate cryptographic applications using V-extension. This includes following extensions:

  • Zvk - Vector Crypto (rollup of all of the following extensions)

  • Zvbb - Vector Bit-manipulation used in Cryptography

  • Zvbc - Vector Carryless Multiplication

  • Zvkg - Vector GCM/GMAC

  • Zvkned - NIST Suite: Vector AES Block Cipher

  • Zvknha - NIST Suite: Vector SHA-2 Secure Hash: SHA-256

  • Zvknhb - NIST Suite: Vector SHA-2 Secure Hash: SHA-512 and SHA-256

  • Zvksed - ShangMi Suite: SM4 Block Cipher

  • Zvksh - ShangMi Suite: SM3 Secure Hash

  • Zvkn - NIST Algorithm Suite

  • Zvknc - NIST Algorithm Suite with carryless multiply

  • Zvkng - NIST Algorithm Suite with GCM

  • Zvks - ShangMi Algorithm Suite

  • Zvksc - ShangMi Algorithm Suite with carryless multiplication

  • Zvksg - ShangMi Algorithm Suite with GCM

  • Zvkt - Vector Data-Independent Execution Latency

This extension is part of the Unprivileged Specification.
