Add rand_chacha/OWNERS am: 4f8fff8eb7 am: 9a98bc1413 am: affa0c121f am: 4e51ca7cec Original change: https://android-review.googlesource.com/c/platform/external/rust/crates/rand_chacha/+/1429107 Change-Id: I800db1672525971116c358fca36e902d0e5b65e2
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
[^1]: D. J. Bernstein, ChaCha, a variant of Salsa20
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.
