傳回做為十六進位字串的 X.509v3 憑證公開金鑰。
public:
virtual System::String ^ GetPublicKeyString();
C#
public virtual string GetPublicKeyString();
abstract member GetPublicKeyString : unit -> string
override this.GetPublicKeyString : unit -> string
Public Overridable Function GetPublicKeyString () As String
做為十六進位字串的 X.509 憑證公開金鑰。
下列範例會 GetPublicKeyString 使用 方法,將憑證的公鑰當做字串傳回,並將其顯示至控制台。
using namespace System;
using namespace System::Security::Cryptography::X509Certificates;
int main()
{
// The path to the certificate.
String^ Certificate = "Certificate.cer";
// Load the certificate into an X509Certificate object.
X509Certificate^ cert = X509Certificate::CreateFromCertFile( Certificate );
// Get the value.
String^ results = cert->GetPublicKeyString();
// Display the value to the console.
Console::WriteLine( results );
}
C#
using System;
using System.Security.Cryptography.X509Certificates;
public class X509
{
public static void Main()
{
// The path to the certificate.
string Certificate = "Certificate.cer";
// Load the certificate into an X509Certificate object.
X509Certificate cert = X509Certificate.CreateFromCertFile(Certificate);
// Get the value.
string results = cert.GetPublicKeyString();
// Display the value to the console.
Console.WriteLine(results);
}
}
Imports System.Security.Cryptography.X509Certificates
Public Class X509
Public Shared Sub Main()
' The path to the certificate.
Dim Certificate As String = "Certificate.cer"
' Load the certificate into an X509Certificate object.
Dim cert As X509Certificate = X509Certificate.CreateFromCertFile(Certificate)
' Get the value.
Dim results As String = cert.GetPublicKeyString()
' Display the value to the console.
Console.WriteLine(results)
End Sub
End Class
這個值會對應至憑證內 SubjectPublicKeyInfo 數據欄位的內容 subjectPublicKey
。
