Struct Tls13KeySchedule 

pub struct Tls13KeySchedule { /* private fields */ }

TLS 1.3 Key Schedule

Manages the key derivation process for TLS 1.3 connections.

Implementations

impl Tls13KeySchedule

pub fn new(shared_secret: &[u8]) -> Self

Create a new TLS 1.3 key schedule

Arguments

• shared_secret - Shared secret from key exchange (e.g., ECDHE)

pub fn derive_handshake_secrets( &mut self, client_hello: &[u8], server_hello: &[u8], ) -> ([u8; 32], [u8; 32])

Derive handshake traffic secrets

Arguments

• client_hello - Client hello message
• server_hello - Server hello message

Returns

Tuple of (client_handshake_traffic_secret, server_handshake_traffic_secret)

pub fn derive_application_secrets(&self) -> Tls13Result<([u8; 32], [u8; 32])>

Derive application traffic secrets

Returns

Tuple of (client_application_traffic_secret, server_application_traffic_secret)

pub fn derive_exporter_secret(&self) -> Tls13Result<[u8; 32]>

Derive exporter master secret

Used for exporting keying material outside of TLS

pub fn derive_resumption_secret( &self, transcript_hash: &[u8], ) -> Tls13Result<[u8; 32]>

Derive resumption master secret

Used for session resumption

pub fn update_traffic_secret(current_secret: &[u8; 32]) -> [u8; 32]

Update traffic keys (key update)

Derives new traffic secret from current one
