using System.Security.Cryptography.X509Certificates; X509Certificate cert = new X509Certificate("myCertificate.cer"); int hashCode = cert.GetHashCode();
using System.Security.Cryptography.X509Certificates; byte[] certData = GetDataFromServer(); X509Certificate cert = new X509Certificate(certData); int hashCode = cert.GetHashCode();In this example, we retrieve certificate data from a server using a custom method named GetDataFromServer(). We create an instance of the X509Certificate class using the retrieved data and call the GetHashCode() method to get the hash code for that certificate. The System.Security.Cryptography.X509Certificates namespace is part of the .NET Framework Class Library.
