# sip-hash

A Common Lisp implementation of SipHash, a cryptographically strong family of
hash functions designed by Jean-Philippe Aumasson and Daniel J. Bernstein.

For more information see the [SipHash web site](http://131002.net/siphash) and
the [SipHash reference implementation](https://github.com/veorq/SipHash).

## The sip-hash API

#### hash-64-2-4 octets k0 k1 &key (start 0) (end (length octets))

```
Returns as an (unsigned-byte 64) the 64-bit SipHash-2-4 hash code for
positions START through END of OCTETS, using the initial state stored in K0
and K1.
```

#### hash-64-4-8 octets k0 k1 &key (start 0) (end (length octets))

```
Returns as an (unsigned-byte 64) the 64-bit SipHash-4-8 hash code for
positions START through END of OCTETS, using the initial state stored in K0
and K1.
```

#### hash-128-2-4 octets k0 k1 &key (start 0) (end (length octets))

```
Returns as two (unsigned-byte 64) values the 128-bit SipHash-2-4 hash code
for positions START through END of OCTETS, using the initial state stored
in K0 and K1.
```

#### hash-128-4-8 octets k0 k1 &key (start 0) (end (length octets))

```
Returns as two (unsigned-byte 64) values the 128-bit SipHash-4-8 hash code
for positions START through END of OCTETS, using the initial state stored
in K0 and K1.
