(Node.js) Load PEM Public/Private Key into RSA Object

Demonstrates how to load a PEM key into the Chilkat RSA object.

Install Chilkat for Node.js and Electron using npm at Chilkat npm packages for Node.js Chilkat npm packages for Electron on Windows, Linux, MacOS

var os = require('os');
if (os.platform() == 'win32') {  
  var chilkat = require('@chilkat/ck-node23-win64');

    if (os.arch() == 'arm') {

    } else if (os.arch() == 'arm64') {

    // This example assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    var rsa = new chilkat.Rsa();

    // First demonstrate importing a PEM public key:
    var publicKeyPem = "PEM public-key data goes here";
    var pubkey = new chilkat.PublicKey();

    var success = pubkey.LoadFromString(publicKeyPem);
    if (success !== true) {
        console.log(pubkey.LastErrorText);
        return;
    }

    var publicKeyXml = pubkey.GetXml();

    success = rsa.ImportPublicKey(publicKeyXml);
    if (success !== true) {
        console.log(rsa.LastErrorText);
        return;
    }

    // Demonstrate importing a PEM private key:
    var privateKeyPem = "PEM private-key data goes here";
    var privkey = new chilkat.PrivateKey();

    // If the private key PEM is protected with a password, then 
    // call LoadEncryptedPem.  Otherwise call LoadPem.
    success = privkey.LoadPem(privateKeyPem);
    if (success !== true) {
        console.log(privkey.LastErrorText);
        return;
    }

    var privateKeyXml = privkey.GetXml();
    success = rsa.ImportPrivateKey(privateKeyXml);

        console.log(rsa.LastErrorText);
        return;
