icodebroker MICROSOFT 2024-06-19

■ ServicePointManager 클래스의 ServerCertificateValidationCallback 속성을 사용해 특정 인증서 오류를 무시하는 방법을 보여준다.

▶ 예제 코드 (C#)


using System.Net;
using System.Net.Security;
using System.Security.Cryptography.X509Certificates;

ServicePointManager.ServerCertificateValidationCallback += delegate (object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors)
{
    if(sslPolicyErrors == SslPolicyErrors.None)
    {
        return true;
    }

    if(certificate.GetCertHashString() == "99E92D8447AEF30483B1D7527812C9B7B3A915A7")
    {
        return true;
    }

    return false;
};
