See the IETF Specification for more information

Installation

Either commands, from Package Manager Console or .NET Core CLI, will download and install the package.

Usage

using SecurityDataParsers.SubjectAlternativeName;

// Load the certificate you want get data from
var cert = new X509Certificate2("path/to/certificate.pfx", "password");

// Get the SAN extension
var sanExtension = cert.Extensions["2.5.29.17"];
// Parse the SAN extension
var san = new SAN(sanExtension);

// Or let the SAN class extract it itself
var san = new SAN(cert);


// Destructure the SAN extension to get its properties
var (
  fASCN,
  principalName,
  rfc822Name,
  dnsName,
  x400Address,
  directoryName,
  ediPartyName,
  uniformResourceIdentifier,
  iPAddress,
  registeredID
) = san.First;

// Use the properties as needed
Console.WriteLine($"FASCN: {fASCN.personIdentifier}");
Console.WriteLine($"Principal Name: {principalName}");

// If it contains multiples, the base class contains lists you can check.
san.dnsNames.Select(v => Console.WrtitLine(v.Host))
