# CRNDM - Generate Random Numbers with Hardware

[![Go Reference](https://pkg.go.dev/badge/github.com/SeanTolstoyevski/crndm.svg)](https://pkg.go.dev/github.com/SeanTolstoyevski/crndm)

## Benchmark Results:

### Note

`Rdrand` and `Rdseed` instructions  are **not designed for speed**. Moreover, the process is even slower because Golang cannot inline assembly codes.
