Step 1: Intro

Hey guys, this is Blurryface21. In this Instructable, I'll be showing you all how to create a text encryptor and decryptor with a batch file.

Step 2:

Alright, all you gotta do is copy and paste the below code into a notepad file, and save it as anything.bat. Make sure you save the file type as all.

Step 3: You're Done!

Now, just save the file, run it, and you've got a batch encryptor/decryptor tool!

<p>I'm pretty sure I saw this identical code here a short time ago (along with a comment of mine that Cesar's code is fun, but not safe). If you want someone to use your code you should post it in a way that it can be used. The above will simply cause your bat interpreter to croak.</p>
