Nym Sphinx webassembly client
Produces layer-encrypted Sphinx packets for use with Nym mixnets.
Sphinx packets ensure the privacy of information in transit, even when the adversary is able to monitor the network in its entirety. When used with a mixnet, both content (what you said) and metadata (who you said it to, when you said it) are protected.
This helps browser-based and mobile applications get stronger privacy, in a way that wasn't previously possible.
This client is part of the Nym project. It's written in Rust and compiled to WebAssembly.
Security Status
From a security point of view, this module is not yet complete. Key missing features include, but are not limited to: cover traffic, sending packets with delay according to Poisson distribution.
They should be implemented soon. You can build your applications, but don't rely on it for strong anonymity yet if your application needs cover traffic.
Using it
See the SDK directory for examples on how to use it and the NPM packages available.
Developing
This is a Rust crate which is set up to automatically cross-compile the contents of src to WebAssembly (aka wasm). It's published from the main Nym platform monorepo in the clients/webassembly directory.
First, make sure you've got all the Rust wasm toolchain installed. Cross-compilation sounds scary, but the Rust crew have enabled a remarkably simple setup.
Furthermore, wasm-bindgen documentation provides excellent tips to solving common problems.
Whenever you change any Rust in the src directory, run wasm-pack build --scope nymproject to update the built wasm artefact in the pkg directory.
To be clear, this is not something that most JS developers need to worry about, this is only for Nym devs. The packages on NPM have all files in place. Just install and enjoy!
Packaging
If you're a Nym platform developer who's made changes to the Rust files and wants to re-publish the package to NPM, here's how you do it:
- bump version numbers as necessary for SemVer
- go the
sdk/typescriptdirectory (off the project root) - run:
yarn
yarn build
yarn publish
