RSA Encrypt and OpenSSL Decrypt

Demonstrates how to use Chilkat to RSA encrypt, and then use OpenSSL to decrypt. Node.js

NODEJS_PRELUDE

function chilkatExample() {

    var success = false;

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

    var rsa = new chilkat.Rsa();

    var privKey = new chilkat.PrivateKey();
    success = rsa.GenKey(2048,privKey);
    success = privKey.SavePkcs8PemFile("qa_output/privKey.pem");

    var pubKey = new chilkat.PublicKey();
    privKey.ToPublicKey(pubKey);

    rsa.EncodingMode = "base64";
    var plainText = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz01234567890";
    var bUsePrivateKey = false;
    rsa.UsePublicKey(pubKey);
    var encryptedStr = rsa.EncryptStringENC(plainText,bUsePrivateKey);

    var bd = new chilkat.BinData();
    bd.AppendEncoded(encryptedStr,"base64");
    success = bd.WriteFile("qa_output/enc.dat");

    // The OpenSSL command to decrypt is:
    // openssl pkeyutl -in enc.dat -inkey privKey.pem -keyform PEM -pkeyopt rsa_padding_mode:pkcs1 -decrypt

    console.log("OK");
