No. First of, they are explicitly comparing to ChaCha20.
Secondly, ChaCha1–7 aren’t a thing, outside of a cryptanalysis paper anyway. Primitives like ChaCha need a certain number of rounds to do what they do.
Finally, ChaCha8 doesn’t just “pass statistical tests,” it’s cryptographically secure.
- bjoli 6y agoOf course chacha1-7 is a thing. Just not for cryptography. I used 4 rounds of salsa to create random-looking numbers just for fun (4 rounds is what you need to get good diffusion), and I know for a fact that I am not alone in having the idea. The reason nobody uses it like that is that it is slower than most other PRNGs
