crypto/tls, now with 100% more 1.3.

THE API IS NOT STABLE AND DOCUMENTATION IS NOT GUARANTEED.

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 1.8rc3 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. If the value is short, only the error and the first meaningful stack frame are printed.

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 BoringSSL/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: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
