This repository provides cryptographic tools for digital democracies.

Other than the compilation as a static or shared lib, it also compiles for WASM and use in the browser.

The code has not undergone any external security audits yet. Use at your own risk.

Introduction

This library relies heavily on Ed25519 public-secret key pairs and their related operations, which are provided by libsodium, which is a battle-tested project.

In the src folder, there are the functions that enable private liquid democracy according to this paper. There is an example in the tests folder.

It also has Shamir secret sharing functionality, where a user can split and restore a secret through the Shamir threshold sharing scheme.

The library also has mnemonic generation, validation and Ed25519 key pair from mnemonic functionality that was inspired by bip39 but instead of Blake2b we use Argon2 and instead of SHA256 we use SHA512, both of which can be found in libsodium.

Finally, you can calculate Merkle roots, proofs and validate proofs from trees.

Files

The chacha20poly1305 directory contains symmetric and asymmetric key encryption functions. The schema is AEAD and the IETF implementation. The Ed25519 keys are converted to x25519 for key agreement.

The merkle directory contains a Merkle root getter function, a Merkle proof artifacts getter, a root from proof getter and a proof verification function.

The shamir directory contains a Shamir secret split and restoration of a Uint8Array secret. Under the hood it uses the libsodium randombytes method to generate random coefficients for the polynomial.

The utils directory contains helper methods such as cryptographic random slicing of arrays etc.

Getting Started

To get started you need to have CMake, LLVM/Clang and emsdk installed on your machine and in your path. You also need to clone this repository and libsodium as a submodule in order to be able to compile the library

git clone git@github.com:ondemos/core.git ondemos cd ondemos git submodule update --init --recursive source ./build.sh

The build script will also compile and run the files in the tests folder. For now this only tests the private liquid voting functionality.
