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].

## Crate Features
`rand_chacha` is `no_std` compatible. It does not require any functionality
outside of the `core` lib, thus there are no features to configure.

Apache License (Version 2.0).

incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor

A cryptographically secure random number generator that uses the HC-128
algorithm.
HC-128 is a stream cipher designed by Hongjun Wu[^1], that we use as an
RNG. It is selected as one of the "stream ciphers suitable for widespread
adoption" by eSTREAM[^2].

## Crate Features
`rand_hc128` is `no_std` compatible. It does not require any functionality
outside of the `core` lib, thus there are no features to configure.
