Struct hina::crypto::SipHasher24

pub struct SipHasher24 { /* fields omitted */ }

an implementation of siphash 2-4.

see: https://131002.net/siphash/

siphash is a general-purpose hashing function: it runs at a good speed (competitive with spooky and city) and permits strong keyed hashing. this lets you key your hashtables from a strong rng, such as rand::os::OsRng.

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 strongly discouraged.

Methods

impl SipHasher24

pub fn new() -> SipHasher24

creates a new siphasher24 with the two initial keys set to 0.

pub fn new_with_keys(key0: u64, key1: u64) -> SipHasher24

creates a siphasher24 that is keyed off the provided keys.
