OpenSSL .NET c# wrapper X509 certification

Question

Hi Iam using the OpenSSL .NET wrapper in my c# project. i want to generate an X509 certification but i don\'t really know the procedure. what should it contain (what parameters)

Answer 1

I use the following routine:

// Initialize the following with your information
var serial = 1234;
var issuer = new X509Name("issuer");
var subject = new X509Name("subject");

// Creates the key pair
var rsa = new RSA();
rsa.GenerateKeys(1024, 0x10001, null, null);

// Creates the certificate
var key = new CryptoKey(rsa);
var cert = new X509Certificate(serial, subject, issuer, key, DateTime.Now, DateTime.Now.AddYears(20));

// Dumps the certificate into a .cer file
var bio = BIO.File("C:/temp/cert.cer", "w");
cert.Write(bio);
