See more Secrets Examples

Demonstrates how to fetch the content of a binary secret from the Azure Key Vault.

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

Objective-C

#import <CkoSecrets.h>
#import <CkoJsonObject.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.

//  The bootstrap secret will contain the following information:

//  Azure Tenant ID
//  Azure Client ID
//  Azure Client Secret

//  See following examples for setting up a bootstrap secret in memory, 
//  or in the local manager (Windows Credentials Manager or Apple Keychain)
//  Setup Bootstrap Secret in Local Manager
//  Setup Bootstrap Secret in Memory
CkoSecrets *bootstrap = [[CkoSecrets alloc] init];

//  Set the location of the bootstrap secret.
//  Can be "local_manager" or "memory", depending on how you setup the bootstrap secret.
//  ---------------------------------------------------------------------------------------------
//  If your operating system is NOT Windows or MacOS/iOS, then change "local_manager" to "memory"
//  You can also, if desired, use "memory" on Windows and MacOS/iOS if your bootstrap secret was previously setup in memory.
//  ---------------------------------------------------------------------------------------------
bootstrap.Location = @"local_manager";

//  Specify the bootstrap secret to be used.
CkoJsonObject *bsId = [[CkoJsonObject alloc] init];
[bsId UpdateString: @"appName" value: @"azure_bs"];
[bsId UpdateString: @"service" value: @"Example"];
[bsId UpdateString: @"username" value: @"Joe"];

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

secrets.Location = @"azure_key_vault";
success = [secrets SetBootstrapSecret: bsId secretContent: bootstrap];
if (success == NO) {
    NSLog(@"%@",secrets.LastErrorText);
    return;
}

//  Specify the secret to be fetched.
CkoJsonObject *json = [[CkoJsonObject alloc] init];
[json UpdateString: @"appName" value: @"Test2"];
[json UpdateString: @"service" value: @"Custom"];
[json UpdateString: @"domain" value: @"Ocean"];
[json UpdateString: @"username" value: @"Starfish"];

//  For Azure Key Vault, we also need to specify the name of the vault where the secret is located.
//  Replace "kvChilkat" with the name of your key vault.
[json UpdateString: @"vaultName" value: @"kvChilkat"];

//  Get the binary secret data.
CkoBinData *bd = [[CkoBinData alloc] init];
success = [secrets GetSecretBd: json bd: bd];
if (success == NO) {
    NSLog(@"%@",secrets.LastErrorText);
    return;
}

//  For our testing, the binary secret was a JPG image..
[bd WriteFile: @"c:/temp/qa_output/starfish.jpg"];

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