In real world though anything but the lowest end hardware will have cryptographic offloads either in the CPU or storage controller (or both). The M1 actually excels at AES throughput for instance.
For esoteric/custom crypto it could play a part though but you have to have good reasons to not want to use standard crypto at higher speed for it to be your use case which is why I say it'd be uncommon.
