Hi,I got a Service Account private key from Google (Something like "MIIEvAIBADAN....uWqbWl871RnFOg==". In fact the key is larger than this. It is 1649 characters long.I try to get a SecKey from it but i always get nil.Here is the code from a playground:let privateKey = "MIIEvAIBADANBgkqhki.......s6ipqUCFro0XLj/5q5Oh+1C9drU\ncz+fZlCRuWqbWl871RnFOg==" // Get a Private key for a service account from Googlelet privateKeyData = privateKey.data(using: String.Encoding.utf8)let base64privateKeyData = privateKeyData?.base64EncodedData()let keyDict:[NSObject:NSObject] = [ kSecAttrKeyType: kSecAttrKeyTypeRSA, kSecAttrKeyClass: kSecAttrKeyClassPrivate, kSecAttrKeySizeInBits: NSNumber(value: 4096), kSecReturnPersistentRef: true as NSObject]let cfData = base64privateKeyData! as CFDatavar error: Unmanaged<CFError>?let publicKey = SecKeyCreateWithData(cfData, keyDict as CFDictionary, &error)NSLog(error.debugDescription)In Xcode 9.0 i can't get the error.debugDescription, but in previous version it contains a code 50 errorIs there a problem with the SecKeyCreateWithData function? or am i making some mistake?Thanks,Fernando
