MD5Simply is simply a very simple tiny MD5 Encryption class for Android. You might find the same code all over the internet. But one big question remained: why DRY? So you don't have to create the same class yourself but simply use MD5Simply. It is very useful to work with SharedPreferences. And you see an example of using MD5 with SharedPreferences below.
- Download MD5Simply.jar
- Copy it and paste into your Android project at App > libs > right click on the jar file and choose Add as Library
import com.kosalgeek.android.md5simply.MD5;
[...]
String yourText = "this is your normal text";
String md5Text = MD5.encrypt(yourText);
// that's it!//Write Username and MD5 Password to SharedPreferences
SharedPreferences pref = getSharedPreferences("pref.txt", Context.MODE_PRIVATE);
SharedPreferences.Editor editor = pref.edit();
editor.putString("username", "oumsaokosal");
editor.putString("password", MD5.encrypt("kosalgeek"));
editor.apply();
[...]
//Read Username and Password from SharedPreferences
SharedPreferences pref = getSharedPreferences("pref.txt", Context.MODE_PRIVATE);
String username = pref.getString("username", "");
String password = pref.getString("password", "");
Log.d(TAG, username);
Log.d(TAG, password);
//Compare
String enteredUsername = "oumsaokosal";
String enteredPassword = "kosalgeek";
String md5Password = MD5.encrypt(enteredPassword);
if(enteredUsername.equals(username) && md5Password.equals(password)){
Log.d(TAG, "same");
}
else{
Log.d(TAG, "different");
}
//Of course, the result is "same"- Get more free source code at https://github.com/kosalgeek
