Make rand_chacha available to product and vendor am: 63509b91b6 am: e7eaedf402 am: cb18d8725f Original change: https://android-review.googlesource.com/c/platform/external/rust/crates/rand_chacha/+/2476394 Change-Id: I430db5be3f6d2136159d5090015b84a15e8c292e Signed-off-by: Automerger Merge Worker <[email protected]>
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.

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.
