Update Android.bp by running cargo_embargo am: fd3a67b5d4 Original change: https://android-review.googlesource.com/c/platform/external/rust/crates/rand_chacha/+/3208620 Change-Id: I2260dca9dcaf15e60a32e3dadff30c8dbe62692e 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.
