title: Using a X509 certificate for decryption
body: <p>I have some data of an X509v3 certificate that is used at a central licensing station. My question is is the following amount of information enough for me to decrypt data using C# code? And additionally, how are the certificate properties imported into a project? Do I have to create a certificate file in order to go on?</p>
  
  <p>Known to me are:</p>
  
  <ul>
  <li>Subject</li>
  <li>Serial Number</li>
  <li>Issuer</li>
  <li>"root-ca"</li>
  <li>Public Key Algorithm: "rsaEncryption"</li>
  <li>RSA Modulus, 128 bytes</li>
  <li>RSA Public Key Exponent</li>
  <li>X509v3 Extended Key Usage: "critical"</li>
  <li>Signature Algorithm: "md5WithRSAEncryption", followed by 256 untitled bytes</li>
  <li>SHA1 Fingerprint</li>
  </ul>
  
  <p>I do not have any certificate file. Excuse me if a similar question has already been answered, unfortunately I wasn't able to find one like mine.</p>
