Hi,

I am working on iPhone. I wanted to get a certificate that contains a
particular value in the subject field. Eg. CN="myName" or O="myOrg" etc. I
tried to use the SecItemCopyMatching with kSecMatchSubjectContains. but the
certificate returned is not having the same subject name.

The example code as below.

err = SecItemCopyMatching(
                                      (CFDictionaryRef) [NSDictionary
dictionaryWithObjectsAndKeys:

 (id)kSecClassCertificate, kSecClass,
                                                         @"CN=MyName",
kSecMatchSubjectContains,

 kSecMatchLimitOne,      kSecMatchLimit,
                                                         kCFBooleanTrue,
     kSecReturnRef,

 kCFBooleanTrue,         kSecReturnAttributes,
                                                         nil
                                                         ],
                                      (CFTypeRef *) &result1
                                      );

or I got the subject field which is in x.500 format. How to extract CN,
organization details from the x.500 formatted NSData?

Regards,
SivaKumar
