Load P7B and List Certificates

Demonstrates how to load a .p7b containing certificates and accesses each individual certificate. Objective-C

#import <CkoPem.h>
#import <CkoCert.h>

BOOL success = NO;

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

success = NO;

CkoPem *pem = [[CkoPem alloc] init];

// Load the .p7b from a file.
success = [pem LoadP7bFile: @"/Users/chilkat/testData/p7b/myCerts.p7b"];
if (success != YES) {
    NSLog(@"%@",pem.LastErrorText);
    return;
}

int i;
int numCerts = [pem.NumCerts intValue];
if (numCerts == 0) {
    NSLog(@"%@",(@"Error: Expected the .p7b to contain certificates."));
    return;
}

// Access each certificate and show the DN (Distinguished Name)
for (i = 1; i <= numCerts; i++) {
    CkoCert *cert = [pem GetCert: [NSNumber numberWithInt: (i - 1)]];
    NSLog(@"%d%@%@",i,@": ",cert.SubjectDN);
