Struct rustls::kx::KeyExchange

pub(crate) struct KeyExchange {
    skxg: &'static SupportedKxGroup,
    privkey: EphemeralPrivateKey,
    pub(crate) 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(crate) fn choose( name: NamedGroup, supported: &[&'static SupportedKxGroup], ) -> Option<&'static SupportedKxGroup>

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

pub(crate) 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(crate) fn group(&self) -> NamedGroup

Return the group being used.

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