Struct tlspuffin::tls::rustls::kx::KeyExchange

pub struct KeyExchange {
    pub skxg: &'static SupportedKxGroup,
    pub privkey: EphemeralPrivateKey,
    pub pubkey: PublicKey,
}

An in-progress key exchange. This has the algorithm, our private key, and our public key.

Fields

skxg: &'static SupportedKxGroup

privkey: EphemeralPrivateKey

pubkey: PublicKey

Implementations

impl KeyExchange

pub fn choose(
    name: NamedGroup,
    supported: &[&'static SupportedKxGroup]
) -> Option<&'static SupportedKxGroup>

Choose a SupportedKxGroup by name, from a list of supported groups.

pub fn start(skxg: &'static SupportedKxGroup) -> Option<Self>

Start a key exchange, using the given SupportedKxGroup.

This generates an ephemeral key pair and stores it in the returned KeyExchange object.

pub fn group(&self) -> NamedGroup

Return the group being used.

pub fn complete<T>(
    self,
    peer: &[u8],
    f: impl FnOnce(&[u8]) -> Result<T, ()>
) -> Result<T, Error>

Completes the key exchange, given the peer’s public key.

The shared secret is passed into the closure passed down in f, and the result of calling f is returned to the caller.
