🦅 react-native-falcon

[!IMPORTANT] This is a primitive library used for interacting with the underlying native falcon code. It is not a Falcon LSIG Account; this library only provides the primitives for signing and verifying messages.

Falcon is based on NTRU lattices, used with a hash-and-sign structure.

📦 Installation

react-native-nitro-modules is required as this library relies on Nitro Modules.

pnpm add react-native-falcon react-native-nitro-modules

🚀 Usage

import { FalconModule } from "react-native-falcon";

// 1. Generate a key pair
const { publicKey, privateKey } = FalconModule.generateKey();

// 2. Sign a message
const message = new TextEncoder().encode("Hello, Falcon!").buffer as ArrayBuffer;
const signature = FalconModule.signCompressed(privateKey, message);

// 3. Verify a signature
try {
  FalconModule.verify(publicKey, signature, message);
  console.log("Signature is valid!");
} catch (error) {
  console.error("Signature verification failed:", error.message);
}

// Access constants
console.log(`Public Key Size: ${FalconModule.publicKeySize}`);
console.log(`Private Key Size: ${FalconModule.privateKeySize}`);
