Step by Step

Step 1: Drag the file(s) to encrypt on top of the 
AESCrypt application/shortcut (I put it on my desktop for easy access). Type in your ultra-secret password.


Step 2: AESCrypt encrypts your file and then you can copy it to a USB flash drive (gasp) or email it without fear someone will be able to decrypt it (unless you used a simple, easy to guess password…use a secure password generator and never email the password to the other person since that’s like writing it on a postcard; call them instead).

Note that this encrypted file can be decrypted on Windows, Mac or Linux computers provided the other person has AESCrypt installed and knows the password.

This makes AESCrypt the perfect encryption tool for school administrators who need to email confidential data via GoogleApps for Education.

Practice OpportunityChoose a file you’ve saved from GoogleDocs or a Microsoft Excel file on your computer. Don’t worry, your original file will not be harmed.
