Linux RNG architecture
Introduction
The Linux CSPRNG (cryptographically secure pseudo-random number generator) is one of the most used source of randomness. Its soundness is thus of critical importance for applications using cryptography, such as SSH, web servers or VPN servers. However, the CSPRNG's official documentation might be a bit difficult to digest. This blog article documents its inner workings, focusing on the most important points, so that anyone can easily assess whether the generator meets their requirements and which of its interfaces should be used...
