it could be faster with a hardware chacha20 implementation. if wireguard gets really popular, we might see that eventually. I'd wager a guess that we would get hardware wireguard first though, with fast path acceleration, similar to hardware TLS.
- tatersolid 7y agoModern CPUs are pretty close to being ASICs for ARX ciphers like ChaCha. Add, rotate, and XOR all have dedicated die area. Bernstein designed it that way. Are there any hardware ASIC implementations of ChaCha or are they basically unnecessary?
