Struct HkdfLabelSha256 

pub struct HkdfLabelSha256;

HKDF Labels with SHA256 which are used in HKDF-Extract-Expand Key through TLS 1.3 Key Schedule

Implementations

impl HkdfLabelSha256

pub fn tls13_c_e_traffic(ctx: &[u8; 32]) -> [u8; 54]

pub const fn tls13_res_binder() -> [u8; 20]

pub fn tls13_derived_secret_sha256() -> [u8; 49]

Used for “derived” Application keys phase (same as early_secret feeding handshake)

pub fn tls13_early_secret_sha256() -> [u8; 49]

Early secret has empty SHA256 ctx given no PSK

pub fn tls13_hanshake_finished(hash_len: u8) -> [u8; 18]

pub fn tls13_secret_key(key_len: u8) -> [u8; 13]

pub fn tls13_secret_iv(iv_len: u8) -> [u8; 12]

pub fn tls13_client_handshake_traffic(ctx: &[u8; 32]) -> [u8; 54]

Handshake traffic uses Client+ServerHello Transcript hash for ctx

pub fn tls13_server_handshake_traffic(ctx: &[u8; 32]) -> [u8; 54]

pub fn tls13_client_application_traffic(ctx: &[u8; 32]) -> [u8; 54]

pub fn tls13_server_application_traffic(ctx: &[u8; 32]) -> [u8; 54]
