Hello,
I'm trying to find a way, to programmatically get the password, of current WiFi connection, so I could use the password to connect another device to the same WiFi.
One of the possibilities that I've found was using a terminal command: "security find-generic-password -ga TypeInYourWiFiNameHere | grep “password:”".
Is there any other, more appropriate way to do this in Objective C/C++? Asking user for permission is completely fine and understandable.
The Mac stores the Wi-Fi password in the System keychain. The best way to get it is via CoreWLAN’s CWKeychainFindWiFiPassword function. For example:
import CoreWLAN
func password(for ssid: String) throws -> String {
let ssid = Data(ssid.utf8)
var passwordQ: NSString? = nil
let err = CWKeychainFindWiFiPassword(CWKeychainDomain.system, ssid, &passwordQ)
guard err == noErr else {
throw NSError(domain: NSOSStatusErrorDomain, code: Int(err), userInfo: nil)
}
return passwordQ! as String
}
This will prompt for an admin password. There’s no way to get this info without that prompt, for obvious security reasons.
