Struct tlspuffin::tls::rustls::hash_hs::HandshakeHashBuffer

pub struct HandshakeHashBuffer {
    buffer: Vec<u8>,
    client_auth_enabled: bool,
}

Early stage buffering of handshake payloads.

Before we know the hash algorithm to use to verify the handshake, we just buffer the messages. During the handshake, we may restart the transcript due to a HelloRetryRequest, reverting from the HandshakeHash to a HandshakeHashBuffer again.

Fields

buffer: Vec<u8>

client_auth_enabled: bool

Implementations

impl HandshakeHashBuffer

pub fn new() -> Self

pub fn set_client_auth_enabled(&mut self)

We might be doing client auth, so need to keep a full log of the handshake.

pub fn add_message(&mut self, m: &Message)

Hash/buffer a handshake message.

pub fn get_hash_given(&self, hash: &'static Algorithm, extra: &[u8]) -> Digest

Get the hash value if we were to hash extra too.

pub fn start_hash(self, alg: &'static Algorithm) -> HandshakeHash

We now know what hash function the verify_data will use.

Trait Implementations

impl Clone for HandshakeHashBuffer

fn clone(&self) -> HandshakeHashBuffer

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for HandshakeHashBuffer

fn default() -> HandshakeHashBuffer

Returns the “default value” for a type.
