Struct ServerAuthenticationWorkflow

pub struct ServerAuthenticationWorkflow<'s, D: Digest> { /* private fields */ }

Server-side of the authentication workflow

This struct should be used on the server side to authenticate a compatible SRP6a client. Digest D specifies the digest algorithm used and therefore also implicitly defines the key size of the common secret key.

Implementations

impl<'s, D: Digest> ServerAuthenticationWorkflow<'s, D>

pub fn new(group: &'s SrpGroup) -> Self

pub fn step2(&self, params: ServerStep2Params<'_>) -> Result<ServerStep2Result>

step2: server creates ephemeral key from random bytes and stored verifier

The private key server_private_b must not be exposed, but needs to be stored for future steps. The public key server_public_b and the salt must be sent to the client.

receive: client_public_a from client keep: server_private_a, client_public_b send: server_public_a, salt to client

pub fn step4( &self, params: ServerStep4Params<'_>, ) -> Result<ServerStep4Result<D>>

step4: server-side: generate verifier

the proof() of the result should be sent to the client
