Linux Kernel Configuration
└─>Accelerated Cryptographic Algorithms for CPU (arm)
└─>Hash functions: BLAKE2b (NEON)
In linux kernel since version 4.14.326 (release Date: 2023-09-23)
BLAKE2b cryptographic hash function (RFC 7693)

Architecture: arm using
- NEON (Advanced SIMD) extensions

BLAKE2b digest algorithm optimized with ARM NEON instructions.
On ARM processors that have NEON support but not the ARMv8
Crypto Extensions, typically this BLAKE2b implementation is
much faster than the SHA-2 family and slightly faster than
SHA-1.
