PKCS11 Initialize

See more PKCS11 Examples

The first thing to do to interact with a smart card or USB security token using PKCS11 is to call Initialize. It loads the vendors DLL/shared library and initializes the Cryptoki library. (The Cryptoki library is the DLL/shared lib provided by the smart card vendor.)

Note: This example requires Chilkat v9.5.0.88 or later.

Objective-C

#import <CkoPkcs11.h>

BOOL success = NO;

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

// Note: Chilkat's PKCS11 implementation runs on Windows, Linux, Mac OS X, and other supported operating systems.

CkoPkcs11 *pkcs11 = [[CkoPkcs11 alloc] init];

// You'll need to know in advance the name and possibly the full path to the smart card vendor's shared library.
// On Windows systems it is a .dll.   On Linux it is a .so.  On Mac OS X it will be a .dylib.
// On Windows, if you set the SharedLibPath equal to just the name of the DLL, then it is assumed to be located in the Windows system directory
// which contains dynamic-link libraries and drivers. The Windows system directory is typically C:\Windows\System32

// In this example we will pass just the name of the DLL because it is located in C:\Windows\System32.
// On non-Windows systems you should specify the full path to the shared lib.
// Also use the full path on Windows systems where the smart card vendor's DLL does not install to C:\Windows\System32.
pkcs11.SharedLibPath = @"aetpkss1.dll";

success = [pkcs11 Initialize];
if (success == NO) {
    NSLog(@"%@",pkcs11.LastErrorText);
}
else {
    NSLog(@"%@",@"PKCS11 successfully initialized.");
