ECDSA Node TypeScript

A TypeScript implementation of the Elliptic Curve Digital Signature Algorithm (ECDSA).

Features

• Full TypeScript support with type definitions
• OpenSSL-compatible implementation
• Fast and efficient using Jacobian coordinates
• Supports secp256k1 and prime256v1 (P-256) curves
• Comprehensive test suite

Installation

npm install ecdsa-node-ts
# or
yarn add ecdsa-node-ts

Usage

import { PrivateKey, Ecdsa } from "ecdsa-node-ts";

// Generate new private key
const privateKey = new PrivateKey();

// Get public key
const publicKey = privateKey.publicKey();

// Create message
const message = "My message";

// Create signature
const signature = Ecdsa.sign(message, privateKey);

// Verify signature
const verified = Ecdsa.verify(message, signature, publicKey);
console.log(verified); // true

Working with PEM files

// Import keys from PEM
const privateKeyPem = File.read("privateKey.pem");
const privateKey = PrivateKey.fromPem(privateKeyPem);

const publicKeyPem = File.read("publicKey.pem");
const publicKey = PublicKey.fromPem(publicKeyPem);

// Export keys to PEM
const pemPrivate = privateKey.toPem();
const pemPublic = publicKey.toPem();
