* Add in a RtlGenRandom fallback for non-UWP Windows In some instances BCryptRandom will fail when RtlGenRandom will work. On UWP, we might be unable to actually use RtlGenRandom. Thread the needle and use RtlGenRandom when we have to, when we're able.

getrandom
A Rust library for retrieving random data from (operating) system sources. It is
assumed that the 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 1.36.0 or later.
