See more Certificates Examples

Demonstrates how to load a certificate (.cer) and private key (.pvk) from the files produced by makecert, such as in the following command:

makecert -sv mycertificate.pvk -n "CN=My Simple Certificate" mycertificate.cer -sky Exchange

// First load the .cer file.
// The certificate file (.cer) contains only the certificate (does not include the private key)
CkoCert *cert = [[CkoCert alloc] init];
BOOL success = [cert LoadFromFile: @"qa_data/certs_and_keys/makecert/mycertificate.cer"];
if (success == NO) {
    NSLog(@"%@",cert.LastErrorText);
    return;
}

// Next, load the .pvk file.
// Note: The password "secret" is what you entered when makecert displayed the dialog asking for a password..
CkoPrivateKey *privKey = [[CkoPrivateKey alloc] init];
success = [privKey LoadPvkFile: @"qa_data/certs_and_keys/makecert/mycertificate.pvk" password: @"secret"];
if (success == NO) {
    NSLog(@"%@",privKey.LastErrorText);
    return;
}

// Finally, associate the private key with the certificate.
success = [cert SetPrivateKey: privKey];
if (success == NO) {
    NSLog(@"%@",cert.LastErrorText);
    return;
}

// At this point, the certificate can be used for signing.  For example..
CkoPdf *pdf = [[CkoPdf alloc] init];

// ....
// ....

success = [pdf SetSigningCert: cert];

// ...
// ....

// Some Chilkat classes also provide a method where the cert and private key can be passed separately.
// For example, if SetSigningCert2 is called, then we don't need to explicitly associate the private key with the cert.
success = [pdf SetSigningCert2: cert privateKey: privKey];
