Struct SaltedHasher 

pub struct SaltedHasher { /* private fields */ }

Consistent salted hasher for identifiers.

Implementations

impl SaltedHasher

pub fn new(salt: [u8; 32]) -> Self

Create a new hasher with the given 32-byte salt.

pub fn hash_mac(&self, mac: &[u8; 6]) -> [u8; 6]

Hash a MAC address (6 bytes) to a pseudonymous 6-byte MAC.

Uses SipHash-1-3 (Rust’s DefaultHasher) keyed with the salt. The 64-bit hash output is truncated to 48 bits.

pub fn hash_mac_preserve_oui(&self, mac: &[u8; 6]) -> [u8; 6]

Hash a MAC address preserving the OUI (first 3 bytes).

This allows ML models to identify device manufacturers while still anonymizing the NIC-specific portion.

pub fn hash_bytes(&self, data: &[u8]) -> u64

Hash an arbitrary byte slice to a 64-bit value.
