osrandom

Welcome to osrandom 🎉

A really minimal wrapper around your operating system's cryptographically secure random number generator.

APIs used

The following native APIs are used:

• macOS/iOS: SecRandomCopyBytes from the built-in 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-GNU: getrandom for glibc versions >= 2.25 or /dev/urandom for ancient distributions
• Linux-MUSL: /dev/urandom for ancient distributions
