Step 0: Generate a new verifier v for the user identity I and password P with salt s.

//register s and v send to server

let srp = Client.init(config: Config(prime: N, generator: g, key: key, algorithm: .sha256))

let verifier = client.enroll(identity: _identity, password: _password, salt: salt)

Step 1: Generates a one-time client key A encoded as a hexadecimal.

let userA = client.identify(identity: _identity, password: _password, salt: salt)

Step 2: Create challenge response to server's public key challenge B with a proof of password M1.

let message = try! srp.challenge(B: userB, salt: salt)

//confirm server's proof of shared key message M2 against
srp.confirm(proof: serverPoof)

//calc 256 bit share key
srp.session()
