I was not aware of this! That's kinda fun.

I did an entropy test on my Pi5 (according to https://rob-turner.net/post/raspberrypi-hwrng), and it (7.999832 bits per byte) has about the same entropy as /dev/urandom (7.999831 bits per byte).

However, when using it directly, it's pretty slow. /dev/hwrng is 200 KB/s, /dev/urandom is 40 MB/s.

Though, maybe that doesn't matter if it's just intended to be used to add entropy to the system entropy pool.
