(.NET Core C#) Convert Cert + Key to PEM and PFXThis 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.
Chilkat.Cert cert = new Chilkat.Cert(); Chilkat.PrivateKey privKey = new Chilkat.PrivateKey(); // Load any type of certificate (.cer, .p7b, .pem, etc.) by calling LoadFromFile. bool success = cert.LoadFromFile("qa_data/certs/sample_cert_a.cer"); if (success != true) { Debug.WriteLine(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) { Debug.WriteLine(privKey.LastErrorText); return; } // Write the cert as PEM. success = cert.ExportCertPemFile("qa_output/cert.pem"); // Or get the PEM string directly... Debug.WriteLine(cert.ExportCertPem()); // Associate the private key with the cert object. success = cert.SetPrivateKey(privKey); if (success != true) { Debug.WriteLine(cert.LastErrorText); return; } // Write the cert + private key to a .pfx file. success = cert.ExportToPfxFile("qa_data/myPfx.pfx","password",true); if (success != true) { Debug.WriteLine(cert.LastErrorText); return; } Debug.WriteLine("Success."); |
