Struct Sas

pub struct Sas { /* private fields */ }

A struct representing a short auth string verification object.

This object can be used to establish a shared secret to perform the short auth string based key verification.

Implementations

impl Sas

pub fn new() -> Self

Create a new random verification object

This creates an ephemeral curve25519 keypair that can be used to establish a shared secret.

pub const fn public_key(&self) -> Curve25519PublicKey

Get the public key that can be used to establish a shared secret.

pub fn diffie_hellman( self, their_public_key: Curve25519PublicKey, ) -> Result<EstablishedSas, KeyError>

Establishes a SAS secret by performing a DH handshake with another public key.

Returns an EstablishedSas object which can be used to generate SasBytes if the given public key was valid, otherwise None.

pub fn diffie_hellman_with_raw( self, other_public_key: &str, ) -> Result<EstablishedSas, KeyError>

Establishes a SAS secret by performing a DH handshake with another public key in “raw”, base64-encoded form.

Returns an EstablishedSas object which can be used to generate SasBytes if the received public key is valid, otherwise None.

Trait Implementations

impl Default for Sas

fn default() -> Self

Returns the “default value” for a type.
