keychain

I want to store a symmetric key in the keychain of OS X. I read by the Apple DevDocs that I should use SecItemAdd in order to do this. I also read the CryptoExercise without any solutions for Me. But when I'm doing so, I always got OSStatus errSecNoSuchAttr (-25303) . Codesnippet as follows: //Labels and app tags NSString *label = @"My Testkey"; NSData * peerTag = [[NSData alloc] initWithBytes:(const void *)[label UTF8String] length:[label length]]; // Generating testkey NSMutableData *key = [NSMutableData dataWithLength:kCCKeySizeAES128]; SecRandomCopyBytes(kSecRandomDefault, kCCKeySizeAES128

When building projects in MonoDevelop on the Mac, I get the message "MAC OS X wants to make changes.Type an administrator's name and password to allow this. MAC OSX wants to use system keychain." I found the post Mac OS X wants to use system keychain when compiling the project but this doesn't quite answer my problem. The profiles I installed were done via XCode and are my current/valid profiles on the Provisioning Profile so I assume these are Ok - XCode reports they're valid. I've moved my dev environment from a Macbook (where compiling apps worked fine, without this error) to another Mac

Trying to use SecCopyErrorMessageString to interpret errorCode. in swift : var result: OSStatus result = SecItemAdd(query as CFDictionary, nil); if result != errSecSuccess { let errorDescription = SecCopyErrorMessageString(result,nil) // NSLog("Keychain Error: %@", errorDescription) The error of "Unresolved identifier" starts from "SecCopyError..." The SecCopyErrorMessageString function only became available on iOS in version 11.3. Prior to that, it could only be used on OS X. The above answer is a bit outdated, according to Apple , iOS 11.3, tvOS 11.3 and watchOS 4.3 started to support this

I am trying to use the KeyChainitemwrapper provided by apple. My project is using ARC but I have turned of ARC on KeyChainitemwrapper.m. I linked the 'security.framework' framework to my project. I am getting this linking issue: Undefined symbols for architecture i386: "_main", referenced from: start in crt1.10.6.o ld: symbol(s) not found for architecture i386 clang: error: linker command failed with exit code 1 (use -v to see invocation) I am new to ios development but my guess is that the problem has to do with the fact that the simulator is trying to compile my source targeting i386 rather

This question already has an answer here: Sharing data in between apps in IOS 1 answer I've been doing research on how to share data between applications securely. I'd like to get some info on the correct way to handle this before I do a deep dive on implementation using the wrong method. Just cause you can do something does not necessarily mean you should. User Case : I am working on a suite of language learning apps that have a shared audio file base of several hundred audio files and json files containing important data corresponding to a language. I'd prefer to allow the user to not have
