Imports an RSA private key to the Apple Keychain.

Note: This example requires Chilkat v10.0.0 or greater.

Objective-C

#import <NSString.h>
#import <CkoPrivateKey.h>

BOOL success = NO;

NSString *pemPath = @"/Users/chilkat/qa_data/rsa/rsaPrivKey_pkcs8.pem";
// Provide a password if your PEM is encrypted. Otherwise pass the empty string.
NSString *pemPassword = @"";

CkoPrivateKey *privKey = [[CkoPrivateKey alloc] init];
success = [privKey LoadAnyFormatFile: pemPath password: pemPassword];
if (success == NO) {
    NSLog(@"%@",privKey.LastErrorText);
    return;
}

// In Apple Keychain, the label for an item such as a private key is a user-friendly identifier that helps distinguish one item from
// another in the Keychain. It is typically a brief name or description associated with the item. 
// The label is displayed in the Keychain Access application and is useful for quickly identifying the purpose
// or source of a specific key, certificate, or password entry.

// The label does not affect the functionality or security of the item; it is purely for organizational purposes. 
// You can edit or assign labels to make your Keychain easier to navigate.

// On MacOS, you can save the private key to the Keychain by calling SavePkcs8File with a "filename" in the format"keychain:<label>"
success = [privKey SavePkcs8File: @"keychain:MyRsaKey123"];
if (success == NO) {
    NSLog(@"%@",privKey.LastErrorText);
    return;
}

NSLog(@"%@",@"Success.");
