Struct rustls::hash_hs::HandshakeHashBuffer

pub(crate) 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(crate) fn new() -> Self

pub(crate) fn set_client_auth_enabled(&mut self)

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

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

Hash/buffer a handshake message.

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

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

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

We now know what hash function the verify_data will use.
