getrandom

A Rust library for retrieving random data from (operating) system source. It is assumed that system always provides high-quality cryptographically secure random data, ideally backed by hardware entropy sources. This crate derives its name from Linux's getrandom function, but is cross platform, roughly supporting the same set of platforms as Rust's std lib.

This is a low-level API. Most users should prefer using high-level random-number library like rand.

Usage

Add this to your Cargo.toml:

[dependencies]
getrandom = "0.2"

Then invoke the getrandom function:

fn get_random_buf() -> Result<[u8; 32], getrandom::Error> {
    let mut buf = [0u8; 32];
    getrandom::getrandom(&mut buf)?;
    Ok(buf)
}

For more information about supported targets, entropy sources, no_std targets, crate features, WASM support and Custom RNGs see the getrandom documentation and getrandom::Error documentation.

Minimum Supported Rust Version

This crate requires Rust 1.34.0 or later.
