// Starting in v9.5.0.49, all Chilkat classes can be unlocked at once at the beginning of a program
// by calling UnlockBundle.  It requires a Bundle unlock code.
Chilkat.Global chilkatGlob = new Chilkat.Global();
bool success = chilkatGlob.UnlockBundle("Anything for 30-day trial.");
if (success != true) {
    Debug.WriteLine(chilkatGlob.LastErrorText);

// The Chilkat PEM class was introduced in v9.5.0.49.  
// It requires the bundle to be unlocked, as shown above.
Chilkat.Pem pem = new Chilkat.Pem();

// Load the .p7b from a file.
success = pem.LoadP7bFile("../myCertFiles/myP7b.p7b");
if (success != true) {
    Debug.WriteLine(pem.LastErrorText);
    return;
}

// Note: If the app already has the p7b loaded in memory, the LoadP7b method
// may be called instead.  (see the online reference documentation)

// Iterate over the certificates.
int numCerts = pem.NumCerts;
int i = 0;

while (i < numCerts) {

    Chilkat.Cert cert = pem.GetCert(i);
    Debug.WriteLine("Certificate " + Convert.ToString(i) + " : " + cert.SubjectDN);

    i = i + 1;
