<p>SipHash is a general-purpose hashing function: it runs at a good
speed (competitive with Spooky and City) and permits strong <em>keyed</em>
hashing. This lets you key your hashtables from a strong RNG, such as
<a href="https://doc.rust-lang.org/rand/rand/os/struct.OsRng.html"><code>rand::os::OsRng</code></a>.</p>
<p>Although the SipHash algorithm is considered to be generally strong,
it is not intended for cryptographic purposes. As such, all
cryptographic uses of this implementation are <em>strongly discouraged</em>.</p>
