WireGuard Key Generation in JavaScript
======================================
Various people believe in JavaScript crypto, unfortunately. This small
example helps them fuel their poor taste.
It's possible to generate WireGuard keys (and thus configurations) in the

processes, but it seems pretty hard.
Building
--------
In order to use the example `keygen.html` file, you must first build
the C sources using emscripten. Simply run:
$ make
