Load P7B and Iterate Certificates

See more PEM Examples

Demonstrates how to load a .p7b containing one or more certificates access each of them. 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;

// The Chilkat PEM class was introduced in v9.5.0.49.  
// It requires the bundle to be unlocked, as shown above.
CkoPem *pem = [[CkoPem alloc] init];

// Load the .p7b from a file.
success = [pem LoadP7bFile: @"../myCertFiles/myP7b.p7b"];
if (success != YES) {
    NSLog(@"%@",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 intValue];
int i = 0;

while (i < numCerts) {

    CkoCert *cert = [pem GetCert: [NSNumber numberWithInt: i]];
    NSLog(@"%@%d%@%@",@"Certificate ",i,@" : ",cert.SubjectDN);

    i = i + 1;
}
