Trait rubble::ecdh::SecretKey[−][src]

        self, 
        foreign_key: &PublicKey
    ) -> Result<SharedSecret, InvalidPublicKey>;
}
Expand description

Secret key operations required by Rubble.

This API imposes no requirements on the representation or location of secret keys. This means that it should be possible to implement this trait even for keys stored in some secure key storage like a smartcard.

Required methods

Performs ECDH key agreement using an ephemeral secret key self and the public key of the other party.

Here, “ephemeral” just means that this method takes self by value. This allows implementing SecretKey for providers that enforce single-use keys using Rust ownership (like ring).

Errors

If foreign_key is an invalid public key, implementors must return an error.
