http://arstechnica.com/security/2013/12/we-cannot-trust-intel-and-vias-chip-based-crypto-freebsd-developers-say/ reveals the likelihood that CPU based random number generators "RDRAND" and "Padlock" have been crafted with NSA input too benefit NSA code cracking.
Do the current Ubuntu distros utilize those routines on machines with Intel and VIA CPUs?
If so, can those generators be bypassed by installing other code?
A search on "random number" did not reveal either, and since privacy is important to many, I do believe this is of general interest and not an obscure issue. If the reader agrees, please vote up this question as important to you.
