You can play with the demo at https://opaque.research.cloudflare.com/.

DISCLAIMER: This is a reference implementation only. DO NOT use in production systems.

Getting started

Get the source code:

go get github.com/cloudflare/opaque-ea

Running tests

From the opaque-ea folder, run all tests:

make test

Run a test client and server

Spin up a local server:

  # Set PUBLIC_PATH to path of public folder
  export PUBLIC_PATH="public/"
  # Build the server
  cd https-server && go build main.go && cd ../..
  # Build the client
  cd public/go && GOOS=js GOARCH=wasm go build -o ../main.wasm && cd ../..
  # Start local server
  ./https-server/main

View the result locally at http://localhost:8080/.

Making changes to client

If you make any changes to the client code, you need to re-compile Go to Wasm to see them in your browser.

From the opaque-ea folder:

# Compile go to wasm
cd public/go && GOOS=js GOARCH=wasm go build -o ../main.wasm && cd ../..
