Fort - File encryption software for Windows

Fort is file encryption software for Windows. Fort offers an easy and reliable encryption of files and directories via the Explorer context menu and to protect them with a password. All file types are supported. Fort can be also used to encrypt files and directories in Onedrive, Dropbox and other similar services. Portable version is also available, and allows Fort to be used directly from a USB flash drive.

Why Fort?

Cryptography and data encryption is important. In todays world we are connected all the time. We put our files on different cloud services where they are basically available for the companies running those services and for criminals who might be able to gain access those services. There are many "free" services in which the only way to pay is with your privacy. One might think that "I have nothing to hide". That's not the point. The point is that privacy is a basic human right.

As Bruce Schneier said, "Privacy isn't about hiding something. It's about being able to control how we present ourselves to the world. It's about maintaining a public face while at the same time being permitted private thoughts and actions. It's about personal dignity."

Fort concentrates on encrypting individual files and directories so they can be safely put into a cloud service or similar. Even if you just have sensitive files and data on your laptop locally, what if the laptop gets stolen? Surely you do not want criminals to be able to use the data.

Fort takes security seriously and uses AES with 256bit keys. On decryption Fort checks that the data is not tampered in any way and informs if data tampering is detected. For each file, Fort generates a random initialization vector that is used only once. Similarly, for keys a random one time salt is generated by Fort.
