Load PEM and List Certificates

Demonstrates how to load a PEM 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 LoadPemFile: @"/Users/chilkat/testData/p7b/cacert_mozilla.pem"];
if (success != YES) {
    NSLog(@"%@",pem.LastErrorText);
    return;
}

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

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