#import <CkoCert.h>
#import <NSString.h>
#import <CkoXml.h>

BOOL success = NO;

CkoCert *cert = [[CkoCert alloc] init];

success = [cert LoadFromFile: @"qa_data/certs/sample.cer"];
if (success == NO) {
    NSLog(@"%@",cert.LastErrorText);
    return;
}

// The certificatePolicies OID is 2.5.29.32
NSString *oid = @"2.5.29.32";
NSString *strXml = [cert GetExtensionAsXml: oid];
if (cert.LastMethodSuccess == YES) {
    NSLog(@"%@",strXml);

    // Sample result:
    // <sequence><sequence><oid>2.16.840.1.101.2.1.11.39</oid></sequence></sequence>

    CkoXml *xml = [[CkoXml alloc] init];
    [xml LoadXml: strXml];
    NSLog(@"%@%@",@"Policy OID = ",[xml GetChildContent: @"sequence|oid"]);
