rand_chacha

Build Status Build Status Latest version Book API API Minimum rustc version

A cryptographically secure random number generator that uses the ChaCha algorithm.

ChaCha is a stream cipher designed by Daniel J. Bernstein[^1], that we use as an RNG. It is an improved variant of the Salsa20 cipher family, which was selected as one of the "stream ciphers suitable for widespread adoption" by eSTREAM[^2].

The RNGs provided by this crate are implemented via the fast stream ciphers of the c2-chacha crate.

Crate Features

rand_chacha is no_std compatible when disabling default features; the std feature can be explicitly required to re-enable std support. Using std allows detection of CPU features and thus better optimisation.
