About

Swift bindings for Bandersnatch zero knowledge proof scheme. Using BandersnatchApi interface one can:

• derive ring member key for a given secret key (called entropy);
• create a proof for a given message, list of the ring members (keys) and context;
• sign a message

Installation

Swift Package Manager

Once you have Swift Package Manager setup add package to the dependencies in the Package.swift:

dependencies: [
    .package(url: "https://github.com/novasamatech/verifiable-swift.git", from: "0.2.0")
]

Cocoapods

First, add pod to the Podfile:

pod BandersnatchApi, :git => 'https://github.com/novasamatech/verifiable-swift.git', :tag => '0.2.0'

Then run:

pod install

Bindings creation

In case Rust library is updated one needs to rebuild the binding using the following steps:

1. Update Cargo.toml in the bindings directory to point to the right version of the rust library
2. Run build.sh from the bindings directory
3. In result, new version of the verifyable_crypto.xcframework will be built
