Mark apex-available am: ead2122fd1 Original change: https://android-review.googlesource.com/c/platform/external/rust/crates/rand_chacha/+/3165740 Change-Id: I68334ec28a38918722acfe4765836f2e0026df33 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.
