10A cryptographically secure random number generator that uses the ChaCha
11algorithm.
12
13ChaCha is a stream cipher designed by Daniel J. Bernstein[^1], that we use
14as an RNG. It is an improved variant of the Salsa20 cipher family, which was
15selected as one of the "stream ciphers suitable for widespread adoption" by
16eSTREAM[^2].
17
18The RNGs provided by this crate are implemented via the fast stream ciphers of
19the [`c2-chacha`](https://crates.io/crates/c2-chacha) crate.

35## Crate Features
36
37`rand_chacha` is `no_std` compatible when disabling default features; the `std`
38feature can be explicitly required to re-enable `std` support. Using `std`
39allows detection of CPU features and thus better optimisation.
