X.509 certificates are a generic, highly flexible format. SSL (now known as "TLS") uses X.509 certificates. A "SSL certificate" is a certificate whose contents make it usable for SSL (usually, usable for a SSL server). It uses a custom (simpler) certificate format. My understanding is that this choice was made for non-technical reasons (i.e., because X.509 comes with a lot of baggage and unnecessary complexity). The biggest downside to using certificate-based authentication is that you need to run a certificate authority and manage certificates.
X.509 PKI Certificates Drive Enterprise Security. Since the introduction of the x509 standard for public key infrastructure (PKI) in 1988, x509 PKI and digital certificates have become a critical part of security for enterprises, governments and consumers the world over. When selecting an x509 solution, organizations must consider not only the
2) Submit the CSR to your CA (Certificate Authority) with EKU (Extended Key Usage) extension set to TLS Server (resp. Client) Authentication for the server (resp. clients), in order to get back a proper signed TLS server (resp. client) certificate (signed by the CA). If you don't own a CA, you may create one with keytool and use keytool again
Examples. The following example uses the GetPublicKey method to return a certificate's public key as an array of bytes and displays it to the console.. using namespace System; using namespace System::Security::Cryptography::X509Certificates; int main() { // The path to the certificate.
Here is a sample code for self-signed certificate validation which is derived from azure-IoT-sdk node JS. var deviceCert = { cert: fs.readFileSync (process.env.CERTIFICATE_FILE).toString (), key: fs.readFileSync (process.env.KEY_FILE).toString () }; var transport = new Transport (); var securityClient = new X509Security (registrationId
