wasm

This module allows to compile the Go backend in wasm, so that it can be easily called from javascript. In particular, the following functions are exposed to javascript:

• goNewKeyPairWithProof
• goEncryptVoteWithProof
• goDecryptTallyWithProof
• goAddEncryptedVotes

To compile, run the command make. This will compile the files inside cmd/wasm and place the resulting main.wasm file inside the assets directory.

The file assets/wasm_exec.js is copied from the Go distribution, and performs the necessary setup to call wasm files compiled from Go.

The script assets/index.html allows to invoke the backend functionalities from a browser.

The function loadEVotingBackend(), exported by module assets/wasm_exec_node.js, instead, must be invoked in a Node.js environment before being able to invoke the backend functionalities.

cmd/server is a very basic server for serving the contents of the directory assets, in order to test calling the backend from a browser.
