SecureScuttlebuttHandshakeServer

class SecureScuttlebuttHandshakeServer (source)

Class responsible for performing a Secure Scuttlebutt handshake with a remote peer, as defined in the Secure Scuttlebutt protocol guide

Please note that only handshakes over the Ed25519 curve are supported.

This class manages the state of one handshake. It should not be reused across handshakes. If the handshake fails, a HandshakeException will be thrown.

Functions

create

Creates a new handshake server able to reply to the request of one client

static fun create(ourKeyPair: KeyPair!, networkIdentifier: Bytes32!): SecureScuttlebuttHandshakeServer!

createAcceptMessage

Produces a message to accept the handshake with the client

fun createAcceptMessage(): Bytes!

createHello

Creates a hello message to be sent to the other party, comprised of our ephemeral public key and an authenticator against our network identifier.

fun createHello(): Bytes!

createStream

Creates a stream to allow communication with the other peer after the handshake has completed

fun createStream(): SecureScuttlebuttStreamServer!

readHello

Validates the initial message's MAC with our network identifier, and returns the peer ephemeral public key.

fun readHello(message: Bytes!): Unit

readIdentityMessage

Reads the message containing the identity of the client, verifying it matches our shared secrets.

fun readIdentityMessage(message: Bytes!): Unit
