		blihp on Dec 31, 2021 \| parent \| context \| favorite \| on: Linux Kernel RNG is now Blake2 instead of SHA1 and... The argument that not all CPUs running Linux have hardware SHA2 is valid, and therefore can't be assumed. However saying because one (even a significant one... though it's arguable it hasn't been the majority for a while) doesn't and therefore it shouldn't be used seems shortsighted at best. For decades various minority features have been enabled in the Linux kernel. Since when is lowest common denominator the desirable target to utilize exclusively?

> The argument here is that many (most?) Linux systems have access to a hardware SHA2
