# crypto_api_osrandom

Welcome to `crypto_api_osrandom` 🎉

## About

This crate implements access to your operating system's cryptographically secure random number

generator via [`crypto_api`](https://github.com/KizzyCode/crypto_api).

## APIs used

The following native APIs are used:

 - macOS/iOS: `SecRandomCopyBytes` from the security framework

 - FreeBSD/OpenBSD/NetBSD: `arc4random_buf` (which does not use ARC4 anymore but a secure PRF like

   [ChaCha20](https://cr.yp.to/chacha.html))

 - Windows: `CryptGenRandom` with `PROV_RSA_FULL` as provider

 - Linux: `getrandom` for glibc versions >= 2.25 or `/dev/urandom` for ancient distributions
