[Introvert]

I recently started working on a lot of random projects since I have more free time, and I have made a few cool programs so far.
Today, I am releasing my extension spoofer. It isn't my prettiest code, but it works perfectly.

This works by using the unicode right-to-left-override character, so it is not an exploit or anything, but it should fool some people.

Note that wxPython is required for this to work.
To add more extensions, simply add your desired extension to the dicitionary as a key - and for the value add the extension backwards, without the dot.

If you enjoy this program, it would be appreciated if you posted or left a vouch so other people can see this too.

Thanks!

RTLO character spoofing. Brings back memories of me doing this in C++. And you even used wxPython instead of PyQT. I love it.

Thanks! I was actually thinking of using PyQt but I'm much more comfortable with wxPython. 😁

This one looks nice man :) well done.

This is that file changing exploit that i learnt 1-2 years ago. so this app makes that task easier. wow. amazing. o_O the core of this app is that (u202E) and ofcourse python. haha xD (y)

EDIT: just took the source from pastebin, i am sure this will help me someday.. Thank-you so much for sharing it. really appreciate your efforts! ^_~
