Analysis of Locker 1.0 – Notepad Tricks

Here, in the image given above, I’ve marked the main security bug for the Locker 1.0, due to this simple script of Protecting Data. I’ve thought to make something much more complex and make passwords invisible from the script.

Which, I’ve done in Locker 2.0, where I’ve made this program a little complex. Instead of directly comparing the password in the main script file. I’ve saved the password somewhere else on the HDD, and just reading that file in order to compare passwords, whenever needed. (One of the Notepad Tricks)
