I am new to CSDK, in sample app they used the Platform Trust Store but when i have certificate where to kept in code and how to install on device. what changes I needed given in sample code
CSSecurityPolicyConfiguration *securityPolicyConfig = [[CSSecurityPolicyConfiguration alloc] init];

securityPolicyConfig.continueOnTLSServerIdentityFailure = YES;

securityPolicyConfig.revocationCheckPolicy = CSSecurityPolicyBestEffort;

Hello,

Have you tried to access Avaya Client SDK Communication Package documentation at https://www.devconnectprogram.com/site/global/products_resources/avaya_client_sdk/programming_docs/current/ios/communication/index.gsp?

It has a lot of guides and technical articles for you to learn about the SDK. It might happen that what you are looking for is explained in https://www.devconnectprogram.com/site/global/products_resources/avaya_client_sdk/programming_docs/current/ios/communication/tech/working_certificates.gsp

Best regards,
Artem Tsarev.

I have tried this but not working. Can you tell where i am going wrong?
NSError *error;
NSString* filePath = [[NSBundle mainBundle] pathForResource:@"avaya_cer"
ofType:@"crt"];

// Instantiate a list of certificates.
NSMutableArray* trustedAnchors = [[NSMutableArray alloc] init];
// Populate CA Certificates in the trustedAnchors as required.
[trustedAnchors addObject:filePath];

[self.client.certificateManager setCertificates:trustedAnchors error:&error];
NSLog(@"Certificate Error %@", error);


I am getting "Certificate store error"

1. You need to enable Private trust store:

CSSecurityPolicyConfiguration *securityPolicyConfig = 

    [[CSSecurityPolicyConfiguration alloc] init];

securityPolicyConfig.privateTrustStoreEnabled = true;

2. You should add content of the cert in base64 format (not file path) to "trustedAnchors" array.
You can use "dataWithContentsOfURL" iOS method.

    NSData *certificate = [NSData dataWithContentsOfURL: docFile.url

                                                       options: NSDataReadingUncached

                                                         error: &error];

I have tried this

NSURL *fileURL = [[NSURL alloc] initFileURLWithPath:filePath];
NSData *certificate = [NSData dataWithContentsOfURL: fileURL
options: NSDataReadingUncached
error: &error];

NSString* base64String = [certificate base64EncodedStringWithOptions:0];
NSMutableArray* trustedAnchors = [[NSMutableArray alloc] init];
// Populate CA Certificates in the trustedAnchors as required.
[trustedAnchors addObject:base64String];
[self.client.certificateManager setCertificates:trustedAnchors error:&error];

but still getting error. Can you please tell how populate trustedAnchors array?

Certificate with "crt" extension already contains base64 string. Try to use "certificate" object in "trustedAnchors" array.

I have tried what you mentioned

NSURL *fileURL = [[NSURL alloc] initFileURLWithPath:filePath];
NSData *certificate = [NSData dataWithContentsOfURL: fileURL
options: NSDataReadingUncached
error: &error];
NSMutableArray* trustedAnchors = [[NSMutableArray alloc] init];
// Populate CA Certificates in the trustedAnchors as required.
[trustedAnchors addObject:certificate];
[self.client.certificateManager setCertificates:trustedAnchors error:&error];
NSLog(@"Certificate Error %@", error);

after this i am getting '-[NSConcreteData UTF8String]: unrecognized selector sent to instance 0x17f52eb0' this error.

Otherwise you can use pem certificate and create parser for it like this:

- (NSArray*)parsePemCertificates: (NSData*) data

{

    static NSString * const startCertificate = @"-----BEGIN CERTIFICATE-----";

    static NSString * const endCertificate = @"-----END CERTIFICATE-----";

    

    NSMutableArray* certificates = [[NSMutableArray alloc] init];

    

    NSString* content = [[NSString alloc] initWithData: data encoding: NSUTF8StringEncoding];

    NSScanner *scanner = [NSScanner scannerWithString: content];

    

    while (YES)

    {

        

        NSString *certificate;

        [scanner scanUpToString: startCertificate intoString:nil];

        [scanner scanUpToString: endCertificate intoString: &certificate];

        if (!certificate) {

            break;

        }

        

        certificate = [certificate stringByAppendingString:endCertificate];

        NSLog(@"Parsed certificate %@", certificate);

        [certificates addObject:certificate];

        

    }

    

    return certificates;

}

Thanks lot Pavel_k. You saved my day. :)
