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
