README

OCaml implementation of BLS12-381

Install

# if you implement a library and you don't need an actual implementation
opam install bls12-381
# to target UNIX
opam insall bls12-381-unix
# to target JavaScript, to be used with jsoo.
opam install bls12-381-js

See below how to use in your project.

Run tests

dune runtest
dune build @test/js/browser/serve # Check _build/default/test/js/browser and run `npm run serve`

To get the coverage (only ok for bls12-381-unix and bls12-381-gen)

dune runtest --instrument-with bisect_ppx --force
bisect-ppx-report html

How to use in my project

If you are developing a library using bls12-381, you only need to add bls12-381 in the dependency list. However, if you are writing a binary, three packages are relevant:

  • bls12-381-unix: to be used for UNIX

  • bls12-381-js: to be used to target JavaScript. It does rely on the node packages listed here, version >= 0.8.1, and suppose this module is loaded before in the global namespace under the name _RUSTC_BLS12_381. See test/js/browser/ for an example. You need to use the appropriate package depending on the platform you target (Node or a bundler for the browser). For instance, if you target Node (resp. a bundler like webpack for a browser usage), you must use @dannywillems/rustc-bls12-381-node (resp. @dannywillems/rustc-bls12-381).

  • bls12-381-js-gen: if the module is loaded somewhere else than in the global namespace like the previous package supposes, you can use this third library that provides functors. The functors are expecting a module of the signature:

    sig
      val rust_module : unit -> Jsoo_lib.ESModule.t
    
      val get_wasm_memory_buffer : unit -> Jsoo_lib.Memory.Buffer.t
    end
    

    (note: functions are not directly evaluated values are required because the module might not already be loaded when loading the JavaScript resulting file and the wasm memory buffer being a view over a ArrayBuffer might be invalid if the buffer size is increased at runtime). You can see an example in the src/js.

For more examples, see the test directories.
