hash::siphash+x86_64 +linux

Implements the SipHash keyed hash function. Output of SipHash(secret, input) for any input does not reveal anything about the secret used, which makes it a good choice for use cases that require resistance against hash flooding.

Functions

fn siphash[permalink] [source]

fn siphash(c: u8, d: u8, key: *[16]u8) state;

Creates a [hash::hash] that computes SipHash-c-d with the given 16 byte key, where c denotes number of compression rounds and d denotes number of finalization rounds. Recommended values for c and d are 2 and 4 respectively. Calling hash::close on this function will erase its state information. This function does not provide reset functionality and calling hash::reset on it will terminate execution.

fn sum[permalink] [source]

fn sum(h: *state) u64;

Returns the sum as a u64
