Encrypting files with AES Crypt on Windows and macOS

Please be aware that this application doesn’t allow you to create a fully functioning encrypted file-hosted volume that would retrieve and record your files. Instead AES Crypt is designed to encrypt separate files.

Using AES Crypt on Windows


Download the 32-bit or 64-bit GUI version. Install the program.  Be aware that after the installation you won’t see the launch of the program and the shortcut on your desktop. It is supposed to be so.

One of AES Crypt’s obvious advantages lies in its simplicity. After installing the program, you just choose the file you wish to encrypt.

 Right-click on a file, select AES Encrypt

The encrypted file is a copy of the original file, but with an ".aes" extension. The original file should be deleted.

When you move a file to the recycle bin and empty it, the file is not permanently removed from your hard drive. Files should be deleted with the help of special software you can find out in a separate chapter of this course.


To decrypt a file, right-click on it and in the prompt window enter the correct password.
