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.

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)
• Windows: CryptGenRandom with PROV_RSA_FULL as provider
• Linux: getrandom for glibc versions >= 2.25 or /dev/urandom for ancient distributions

Dependencies

Because this code implements the crypto_api, it depends on the crypto_api-crate. Otherwise, it's dependency less.
