Enum hpke::OpModeS

pub enum OpModeS<'a, Kex: KeyExchange> {
    Base,
    Psk(PskBundle<'a>),
    Auth((Kex::PrivateKey, Kex::PublicKey)),
    AuthPsk((Kex::PrivateKey, Kex::PublicKey), PskBundle<'a>),
}

The operation mode of the HPKE session (sender's view). This is how the sender authenticates their identity to the receiver. This authentication information can include a preshared key, the identity key of the sender, both, or neither. Base is the only mode that does not provide any kind of sender identity authentication.

Variants

Psk(PskBundle<'a>)

A preshared key known to the sender and receiver

Auth((Kex::PrivateKey, Kex::PublicKey))

The identity keypair of the sender

AuthPsk((Kex::PrivateKey, Kex::PublicKey), PskBundle<'a>)

Both of the above
