Dotnet library for reading random numbers from a CPU's digital random number generator (DRNG).

This library contains methods for invoking the RDRAND and RDSEED instructions on Intel and AMD CPUs.

See https://www.intel.com/content/www/us/en/developer/articles/guide/intel-digital-random-number-generator-drng-software-implementation-guide.html for more details

Install the Wetware.ReadRandom package from NuGet (https://www.nuget.org/packages/Wetware.ReadRandom)

using Wetware.ReadRandom;

// Read a random seed value from the CPU
uint seed = Cpu.ReadRandomSeed();

// Read a random value from the CPU
uint random = Cpu.ReadRandom();

• Does not poll the ECX register to determine if RDRAND and RDSEED are supported processor features
• Does not support the REX prefix and can only operate in 32 bit mode.
