Module tls_prf

Source
Expand description

TLS 1.2 PRF API’s for usage in RFC 5246 and RFC 7627.

§Example

use aws_lc_rs::tls_prf::{Secret, P_SHA256};

let pre_master_secret = &[42; 32]; // Value is established during key exchange
let session_hash = &[7; 32]; // Session hash of handshake log

let secret = Secret::new(&P_SHA256, pre_master_secret)?;

let derived_secret = secret.derive(b"extended master secret", session_hash, 48)?;

let derived_secret_bytes = derived_secret.as_ref();

assert_eq!(derived_secret_bytes.len(), 48);

Structs§
