this dumps the TLS ClientHello message to stdout. this might be useful when testing your TLS client settings.

Usage

Install Go 1.19.4.

Add example.com to your hosts file:

echo '127.0.0.1 example.com' | sudo tee --append /etc/hosts >/dev/null

Build and launch the https server:

make
./dist/tls-dump-clienthello_$(go env GOOS)_$(go env GOARCH)_$(go env GOAMD64)/tls-dump-clienthello

Then open https://example.com in the client you want to test.

Open the example-clients directory to see some example clients.

The example clients can also be executed in a Vagrant managed VM. See the Vagrantfile (this requires the base boxes from rgl/windows-vagrant).

Example clients output

• Windows Server 2019 (1809)
• Windows Server 2022 (21H2)
