There's PLENTY of DB leaks contained emails and their respective passwords.
Sometimes, you just want the emails so you can easily have a copy-paste-able place to quickly enter emails.
Well, if you're too lazy to code your own, this python file will clean files for you.
Only applicable to files that use this format:
fakeemail@Email.com:somebadpasswordthatscrackedinseconds othermail@Mailmail.org.ez:12345
etc.
You have to name the file to be sanitized "To be Sanitized"
Of course you can change that by opening the file with a text editor and changing the filename.
This doesn't affect the original file, it just create another file named "Result," so you don't have to worry about all those passwords going away!
