Crypto

A comprehensive cryptographic toolkit for the Lit Protocol SDK that handles secure key operations, encryption/decryption, and advanced cryptographic schemes.

Installation

yarn add @lit-protocol/crypto

Quick Start

import { generateSessionKeyPair, encrypt } from '@lit-protocol/crypto';

// Generate a new key pair
const keyPair = await generateSessionKeyPair();

// Encrypt data with public key and identity param
const encryptedData = await encrypt(
  keyPair.slice(2),
  new Uint8Array([1, 2, 3]),
  new Uint8Array([4, 5, 6])
);
