Fort is a file encryption tool which uses AES-256 to secure your most confidential files.

Explorer integration makes the program generally easy to use. Right-click a file or folder, select Encrypt and enter a passphrase to encrypt it, choose Decrypt and enter the same passphrase to decrypt it: simple.

Extras include an option to generate a secure passphrase at a click, and a launcher to the Windows On-Screen Keyboard which might help you bypass keyloggers.

By default, Fort creates a backup of the original file before encryption, which might not always be convenient. Fortunately you can turn this off in the Settings dialog.

Note that this is the free Home Edition. To use Fort commercially, you'll need to purchase the Professional edition, currently available for $25.
