| <p>ChaCha is a stream cipher designed by Daniel J. Bernstein<sup id="fnref1"><a href="#fn1">1</a></sup>, 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<sup id="fnref2"><a href="#fn2">2</a></sup>.</p> |
| <p>ChaCha uses add-rotate-xor (ARX) operations as its basis. These are safe against timing |
| attacks, although that is mostly a concern for ciphers and not for RNGs. We provide a SIMD |
| implementation to support high throughput on a variety of common hardware platforms.</p> |
| <p>With the ChaCha algorithm it is possible to choose the number of rounds the core algorithm |
| should run. The number of rounds is a tradeoff between performance and security, where 8 |
| rounds is the minimum potentially secure configuration, and 20 rounds is widely used as a |
| conservative choice.</p> |
| <p>We use a 64-bit counter and 64-bit stream identifier as in Bernstein’s implementation<sup id="fnref1"><a href="#fn1">1</a></sup> |
| except that we use a stream identifier in place of a nonce. A 64-bit counter over 64-byte |
| (16 word) blocks allows 1 ZiB of output before cycling, and the stream identifier allows |
| 2<sup>64</sup> unique streams of output per seed. Both counter and stream are initialized |
| to zero but may be set via the <code>set_word_pos</code> and <code>set_stream</code> methods.</p> |
| <p>The word layout is:</p> |
| <div class="example-wrap"><pre class="language-text"><code>constant constant constant constant |
| seed seed seed seed |
| seed seed seed seed |
| counter counter stream_id stream_id</code></pre></div> |
| <p>This implementation uses an output buffer of sixteen <code>u32</code> words, and uses |
| <a href="../rand_core/block/struct.BlockRng.html" title="BlockRng"><code>BlockRng</code></a> to implement the <a href="../rand_core/trait.RngCore.html" title="RngCore"><code>RngCore</code></a> methods.</p> |
