This crate is part of the Tari Cryptocurrency project.

Major features of this library include:

• Pedersen commitments
• Schnorr Signatures
• Generic Public and Secret Keys
• Musig!

The tari_crypto crate makes heavy use of the excellent Dalek libraries. The default implementation for Tari ECC is the Ristretto255 curve.

To build the WebAssembly module, the wasm feature must be enabled:

$ wasm-pack build . -- --features "wasm"

To generate a module for use in node.js, use this command:

$ wasm-pack build --target nodejs -d tari_js . -- --features "wasm"

Note: Node v10+ is needed for the WASM

const keys = KeyRing.new();

// Create new keypair
keys.new_key("Alice");
keys.new_key("Bob");
console.log(`${keys.len()} keys in ring`); // 2
console.log("kA = ", keys.private_key("Alice"));
console.log("PB = ", keys.public_key("Bob"));
keys.free();

To run the benchmarks:

$ cargo bench

The benchmarks use Criterion and will produce nice graphs (if you have gnuplot installed)

To run the benchmarks with SIMD instructions:

$ cargo bench --features "avx2"

To build the C bindings, you can run

make ffi

To build the release version (recommended):

make ffi-release

To run the small demo:

make demo
./bin/demo
