See more Secrets Examples

On Windows, creates or updates a binary secret in the Windows Credentials Manager.

On MacOS or iOS, creates or updates a binary secret in the Apple Keychain.

Note: This example requires Chilkat v10.1.0 or later.

Objective-C

#import <CkoSecrets.h>
#import <CkoJsonObject.h>
#import <NSString.h>
#import <CkoHttp.h>
#import <CkoBinData.h>

BOOL success = NO;

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

CkoSecrets *secrets = [[CkoSecrets alloc] init];

//  On Windows, this is the Windows Credentials Manager
//  On MacOS/iOS, it is the Apple Keychain
secrets.Location = @"local_manager";

//  Specify the name of the secret.
//  service and username are required.
//  appName and domain are optional.
//  Note: The values are arbitrary and can be anything you want.
CkoJsonObject *json = [[CkoJsonObject alloc] init];
[json UpdateString: @"appName" value: @"Test2"];
[json UpdateString: @"service" value: @"Custom"];
[json UpdateString: @"domain" value: @"Ocean"];
[json UpdateString: @"username" value: @"Starfish20"];

//  The purpose of this example is to show how arbitrary binary data
//  can be stored as a secret.

//  We'll use a small JPG image that is approximately 2KB in size.
//  You can test using this same JPG at this URL:
NSString *url = @"https://chilkatdownload.com/sample_data/starfish20.jpg";
CkoHttp *http = [[CkoHttp alloc] init];
CkoBinData *bd = [[CkoBinData alloc] init];
success = [http DownloadBd: url binData: bd];
if (success == NO) {
    NSLog(@"%@",http.LastErrorText);
    return;
}

//  Create or update the binary secret.
success = [secrets UpdateSecretBd: json secret: bd];
if (success == NO) {
    NSLog(@"%@",secrets.LastErrorText);
    return;
}

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