Nym Sphinx in WebAssembly
This is a Rust crate which is set up to automatically cross-compile the contents of lib.rs to WebAssembly (aka wasm).
Wasm is pretty close to bare metal. Browser-based or server-side JavaScript (or other wasm-using environments) can use the wasm output from this crate to create Sphinx packets at much higher speeds than would be possible using (interpreted) JavaScript. This enables browser-based and mobile applications get stronger privacy, in a way that wasn't previously possible.
Compiling
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.
Using it as a JavaScripter
See our docs.
Demo
There's a demo web application in the www folder. To run it, first make sure you've got a recent npm installed, then follow the instructions in its README.
Developing
Whenever you change your Rust, run wasm-pack build to update the built was artefact in the pkg directory.
