Private-ID-Web

WebAssembly variant and accompanying browser interface for Private-ID generation adapted from and inspired by the Rust variant of Private-ID by Facebook Research.

Development Dependencies

The build process for this project requires Rust and Node.js. In addition, it is necessary to install wasm-pack:

cargo install wasm-pack

Don't forget to initialize the original Private-ID source!

git submodule init

Build Process

The build process can be invoked in the following way via the Node package definitions:

npm run-script build # dev: build-debug

Alternatively, it can be invoked directly in the following way:

wasm-pack build --release --no-typescript --target no-modules && npm run-script link-web

Testing

Tests can be invoked in the following way via the Node package definitions:

npm test

Alternatively, they can be invoked directly in the following way:

cd src; cargo run --bin private-id-test

Running in the Browser

Navigate two separate browser tabs or windows to the following two URLs (replacing <localhost> as necessary):

http://<localhost>/index.html?this=aaabcc&other=cccdee  # Party A example.
http://<localhost>/index.html?other=cccdee&this=aaabcc  # Party B example.

(Hosting the web directory can be done with cd web; python -m http.server 3000 and pointing your browser to http://localhost:3000/.)

An example build can be found on the gh-pages branch (Firebase key not included). Images party_a_example.png and party_b_example.png show the UI after a typical run of the protocol.

TODOs

• parallelism using web workers
• compress messages as base64
