Update Android.bp with cargo2android.json am: 5bd3cf7496 am: 11afc841db am: 05ba541042 am: bc14cd029a am: 3896c5fea1 Original change: https://android-review.googlesource.com/c/platform/external/rust/crates/rand_chacha/+/1877118 Change-Id: Ief43f953d0d315ec2b945ec99546708cc44feae7
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.
