Installation

npm install nodeopcua-crypto

Usage

import { generatePrivateKey, privateKeyToPEM, CertificatePurpose, createSelfSignedCertificate } from "./node-opcua-crypto.js";

async function demonstratePrivateKeyAndSelfSignedCertificateCreation() {

    // create the Private Key
    const privateKey = await generatePrivateKey();

    // convert the private key to a PEM format
    const { privPem } = await privateKeyToPEM(privateKey);

    console.log(privPem);

    // create a self-sign certificate
    const { cert } = await createSelfSignedCertificate({
        privateKey,
        notAfter: new Date(2025, 1, 1),
        notBefore: new Date(2019, 1, 1),
        subject: "CN=Test",
        dns: ["DNS1", "DNS2"],
        ip: ["192.168.1.1"],
        applicationUri: "urn:HOSTNAME:ServerDescription",
