Ela is very basic but powerful enough ransomeware by me in AutoIt. It's uses Windows crypt32.dll library to encrypt your files, as there's a bunch of algorithums in crypt32 so we can pickup one of those and add it there. I used AES-256 bit encryption for some creepy works.
To compile this script, you need AutoIt installed on your computer. Download AutoIt from here
