This app does not have help because it is too easy to use. This file will explain everything.
Pick a file that you would like to encrypt/decrypt. Select the option, whether the file should be encrypted or decrypted. Then pick a keyword. In order to decrypt the file you(or someone else) will have to enter the same exact keyword. Without it, the file is useless. If you encrypt the file, AutoEncrypt will create a file with the same name, in the same folder, but will change the extension to "crp". If you decrypt the file, AutoEncrypt will create an original file in the same folder.

I am not responsible for anything that AutoEncrypt may cause. There are no garanties.
