Trait SupportedKxGroup

pub trait SupportedKxGroup:

    // Required methods
    fn start(&self) -> Result<Box<dyn ActiveKeyExchange>, Error>;
    fn name(&self) -> NamedGroup;
}

A supported key exchange group.

This type carries both configuration and implementation. Specifically, it has a TLS-level name expressed using the NamedGroup enum, and a function which produces a ActiveKeyExchange.

Compare with NamedGroup, which carries solely a protocol identifier.

Required Methods

fn start(&self) -> Result<Box<dyn ActiveKeyExchange>, Error>

Start a key exchange.

This will prepare an ephemeral secret key in the supported group, and a corresponding public key. The key exchange can be completed by calling ActiveKeyExchange or discarded.

Errors

This can fail if the random source fails during ephemeral key generation.

fn name(&self) -> NamedGroup

Named group the SupportedKxGroup operates in.

If the NamedGroup enum does not have a name for the algorithm you are implementing, you can use NamedGroup::Unknown.
