Running Sample MsQuic Server and Client

Sample provides a very simple MsQuic API sample server and client application.

Generate Self Signed Certificate

A certificate needs to be available for the server to function. To generate a self-signed certificate, run

On Windows

New-SelfSignedCertificate -DnsName $env:computername,localhost -FriendlyName MsQuic-Test -KeyUsageProperty Sign -KeyUsage DigitalSignature -CertStoreLocation cert:\CurrentUser\My -HashAlgorithm SHA256 -Provider "Microsoft Software Key Storage Provider" -KeyExportPolicy Exportable

This works for both Schannel and OpenSSL TLS providers, assuming the KeyExportPolicy parameter is set to Exportable. The Thumbprint received from the command is then passed to the sample server at startup. Copy the thumbprint received.

On Linux

openssl req  -nodes -new -x509  -keyout server.key -out server.cert

This works with OpenSSL TLS Provider. It can also be used for Windows OpenSSL, however we recommend the certificate store method above for ease of use. Currently key files with password protections are not supported. With these files, they can be passed to the sample server with -cert_file:path/to/server.cert and -key_file path/to/server.key parameters.

Start the server

Locate the quicsample.exe under your artifacts/bin directory under repo root. Start the server providing the thumbrint obtained in the previous step.

quicsample.exe -server -cert_hash:FAF9B176D64930D67C372CB456BAD38E7E5689F7

By default, the server listens on port 4567.

Start the client

Start the client providing the IP address for the server. Here 127.0.0.1 is used as an example.

quicsample.exe -client -unsecure -target:{127.0.0.1}

Console Output

Here is what the console output looks like on the server and client sides after connection is established and data flows:

Description

The quicsample app implements a simple protocol (ALPN "sample") where the client connects to the server, opens a single bidirectional stream, sends some data and shuts down the stream in the send direction. On the server side all connections, streams and data are accepted. After the stream is shut down, the server then sends its own data and shuts down its send direction. The connection only shuts down when the 1 second idle timeout triggers.
