Node.js

Convert Cert + Key to PEM and PFX

See more Certificates Examples

This example is based on the following question from a Chilkat customer:

We receive 2 files :

    MyCertificate.p7b
    MyCertificate-privatekey.pkey

We have to transform these certificate like this:

First convert it to PEM like this:

openssl pkcs7 -in MyCertificate.p7b -inform DER -out MyCertificate.pem -print_certs

Now we get MyCertificate.pem

Last step, we need to convert it to pfx file:

openssl pkcs12 -export -inkey moncertificat-privatekey.pkey  -in  moncertificat.pem -out moncertificat.pfx

Is there a way to make all these steps with Chilkat ?

I will be nice to include this directly in our software instead of askig the user to do it manualy.

function chilkatExample() {

    var success = false;

    var cert = new chilkat.Cert();
    var privKey = new chilkat.PrivateKey();

    // Load any type of certificate (.cer, .p7b, .pem, etc.) by calling LoadFromFile.
    success = cert.LoadFromFile("qa_data/certs/sample_cert_a.cer");
    if (success !== true) {
        console.log(cert.LastErrorText);
        return;
    }

    // Load the private key.
    // (The various privKey methods that load from a file will automatically detect
    // the format.  It doesn't actually matter if you try to load a non-PKCS8 format private key
    // by calling LoadPkcs8EncryptedFile -- internally Chilkat will detect the format and will load
    // based on what it finds.)
    success = privKey.LoadPkcs8EncryptedFile("qa_data/certs/sample_key_a.pkcs8","password");
    if (success !== true) {
        console.log(privKey.LastErrorText);
        return;
    }

    // Write the cert as PEM.
    success = cert.ExportCertPemFile("qa_output/cert.pem");

    // Or get the PEM string directly...
    console.log(cert.ExportCertPem());

    // Associate the private key with the cert object.
    success = cert.SetPrivateKey(privKey);
    if (success !== true) {
        console.log(cert.LastErrorText);
        return;
    }

    // Write the cert + private key to a .pfx file.
    success = cert.ExportToPfxFile("qa_data/myPfx.pfx","password",true);
    if (success !== true) {
        console.log(cert.LastErrorText);
        return;
    }

    console.log("Success.");
