Trait SphinxSuite

pub trait SphinxSuite {

    fn new_shared_keys(
        public_keys: &[<Self::P as Keypair>::Public],
    ) -> Result<SharedKeys<Self::E, Self::G>> { ... }

        secret: &SecretKey16,
        salt: &[u8],
    ) -> Result<IvKey<Self::PRP>> { ... }
}

Represents an instantiation of the Spinx protocol using the given EC group and corresponding public key object.

Required Associated Types

type P: Keypair

Keypair corresponding to the EC group

type E: Scalar + for<'a> From<&'a Self::P>

Scalar type supported by the EC group

type G: GroupElement<Self::E> + for<'a> From<&'a <Self::P as Keypair>::Public>

EC group element

type PRP: StreamCipher + KeyIvInit

Pseudo-Random Permutation used to encrypt and decrypt packet payload

Provided Methods

fn new_shared_keys( public_keys: &[<Self::P as Keypair>::Public], ) -> Result<SharedKeys<Self::E, Self::G>>

Convenience function to generate shared keys from the path of public keys.

fn new_prp_init(secret: &SecretKey) -> Result<IvKey<Self::PRP>>

Instantiates a new Pseudo-Random Permutation IV and key for general packet data.

fn new_reply_prp_init( secret: &SecretKey16, salt: &[u8], ) -> Result<IvKey<Self::PRP>>

Instantiates a new Pseudo-Random Permutation IV and key for reply data.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
