Build Status

Usage

Since crypto/tls is very deeply (and not that elegantly) coupled with the Go stdlib, tls-tris shouldn't be used as an external package. It is also impossible to vendor it as crypto/tls because stdlib packages would import the standard one and mismatch.

So, to build with tls-tris, you need to use a custom GOROOT. A script is provided that will take care of it for you: ./_dev/go.sh. Just use that instead of the go tool.

The script also transparently fetches the custom Cloudflare Go compiler with the required backports.

./_dev/go.sh build ./_dev/tris-localserver
TLSDEBUG=error ./tris-localserver 127.0.0.1:4443

Debugging

When the environment variable TLSDEBUG is set to error, Tris will print a hexdump of the Client Hello and a stack trace if an handshake error occurs.

Building Caddy

./_dev/go.sh build github.com/mholt/caddy

Note: to get Caddy to use TLS 1.3 you'll have to apply the patch at _dev/caddy/caddy.patch.

Testing with Firefox

  1. Download the latest Firefox Nightly
  2. Navigate to about:config and set security.tls.version.max to 4
  3. Connect to https://tris.filippo.io/ or tris-localserver

Testing with BoringSSL/BoGo/NSS/Mint

./_dev/tris-localserver/start.sh --rm
docker build -t tls-tris:boring _dev/boring
docker run -i --rm tls-tris:boring $(docker inspect -f '{{ .NetworkSettings.IPAddress }}' tris-localserver):443
docker build -t tls-tris:bogo _dev/bogo
docker run -i --rm tls-tris:bogo $(docker inspect -f '{{ .NetworkSettings.IPAddress }}' tris-localserver):443
docker build -t tls-tris:tstclnt _dev/tstclnt
docker run -i --rm tls-tris:tstclnt $(docker inspect -f '{{ .NetworkSettings.IPAddress }}' tris-localserver):443
docker build -t tls-tris:mint _dev/mint
docker run -i --rm tls-tris:mint $(docker inspect -f '{{ .NetworkSettings.IPAddress }}' tris-localserver):443
