Struct TlsAuth 

pub struct TlsAuth { /* private fields */ }

TLS-Auth pre-shared HMAC key for control channel authentication

Implementations

impl TlsAuth

pub fn new(key: [u8; 64], direction: u8) -> Self

Create a new TLS-Auth context from key material and direction

pub fn compute_hmac(&self, data: &[u8]) -> [u8; 20]

Compute HMAC-SHA1 over data using the directional key

Uses a simplified HMAC construction: H(key XOR opad || H(key XOR ipad || message)) where H is a simple hash (not cryptographically strong – placeholder for real SHA-1).

pub fn verify_hmac(&self, data: &[u8], expected: &[u8; 20]) -> bool

Verify an HMAC tag against data

Trait Implementations

impl Clone for TlsAuth

fn clone(&self) -> TlsAuth

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
