How to delete all keychain items accessible to an app?
Do it for all classes
Objective-C:
NSArray *secItemClasses = @[(__bridge id)kSecClassGenericPassword,
(__bridge id)kSecClassInternetPassword,
(__bridge id)kSecClassCertificate,
(__bridge id)kSecClassKey,
(__bridge id)kSecClassIdentity];
for (id secItemClass in secItemClasses) {
NSDictionary *spec = @{(__bridge id)kSecClass: secItemClass};
SecItemDelete((__bridge CFDictionaryRef)spec);
}
Swift:
let secItemClasses = [kSecClassGenericPassword, kSecClassInternetPassword, kSecClassCertificate, kSecClassKey, kSecClassIdentity]
for itemClass in secItemClasses {
let spec: NSDictionary = [kSecClass: itemClass]
SecItemDelete(spec)
}
Xamarin iOS version (MonoTouch) of accepted answer on How to delete all keychain items accessible to an app is below:
foreach (var recordKind in new []{
SecKind.GenericPassword,
SecKind.Certificate,
SecKind.Identity,
SecKind.InternetPassword,
SecKind.Key,
})
{
SecRecord query = new SecRecord(recordKind);
SecKeyChain.Remove(query);
}
If you want to make sure you indeed delete the records, you may during development check number of items in KeyChain of specific kind before and after with this code:
SecStatusCode scc;
var records = SecKeyChain.QueryAsRecord(new SecRecord(SecKind.GenericPassword), 1000, out scc);
I rewrote Daij-Djan's answer in Swift:
let secItemClasses = [kSecClassGenericPassword,
kSecClassInternetPassword,
kSecClassCertificate,
kSecClassKey,
kSecClassIdentity]
for secItemClass in secItemClasses {
let dictionary = [kSecClass as String:secItemClass]
SecItemDelete(dictionary as CFDictionary)
}
