Welcome to crypto_api_osrandom 🎉
This crate implements access to your operating system's cryptographically secure random number
generator via crypto_api.
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)
- Windows: CryptGenRandom with PROV_RSA_FULL as provider
- Linux: getrandom for glibc versions >= 2.25 or /dev/urandom for ancient distributions
Because this code implements the crypto_api, it depends
on the crypto_api-crate. Otherwise, it's dependency less.
