See more Cert Store Examples

Demonstrates how to find a certificate having the specified hexadecimal SHA1 thumbprint.

Note: Requires Chilkat v10.1.2 or later.

.NET Core C#

bool success = false;

Chilkat.CertStore certStore = new Chilkat.CertStore();

// This opens the Current User certificate store on Windows,
// On MacOS and iOS it opens the default Keychain.
bool readOnly = false;
success = certStore.OpenCurrentUserStore(readOnly);
if (success == false) {
    Debug.WriteLine(certStore.LastErrorText);
    return;
}

// Find the certificate having a specific SHA1 thumbprint.
Chilkat.JsonObject json = new Chilkat.JsonObject();
string hexThumbprint = "767192374BE3C1512D2CB80734926D40E96D6DC2";
json.UpdateString("thumbprint",hexThumbprint);

Chilkat.Cert cert = new Chilkat.Cert();
success = certStore.FindCert(json,cert);
if (success == true) {
    // Show the full distinguished name of the certificate.
    Debug.WriteLine("Found: " + cert.SubjectDN);
}
else {
    Debug.WriteLine("Not found.");
