Which operating system do you run where time isn't already in the CSPRNG pool?
- CJefferson 9y agoI believe Linux only uses physical devices (which are very limited in some VMs), but this might just be folk-legend (I haven't read the source).
- lvh 9y agoNo, Linux' random.c has add_device_randomness (sp? it's definitely something_device_randomness), which includes a bunch of machine-specific things to the RNG, including MAC addresses, serial numbers, and, crucially, the RTC.
- CJefferson 9y agoI'm obviously misinformed. Thanks for that.
