Fort - Frequently Asked Questions

Is the encryption used by Fort secure?
Yes it is. However, you should keep in mind that no software can be 100% secure. Fort uses Advanced Encryption Standard with the highest possible key length which is 256 bits.
I bought a license, do I need to buy a license for new versions of Fort?
No. Upgrades are free. However, if you need more users than the license allows, then you will need to buy another license for Fort.
Do I need to buy a license to use FortMachine.dll?
No. FortMachine is available as open source under the MIT license. For more information, see for developers section.
I installed Fort, but I can't find any references to Fort from my system?
See Fort usage manual, it available as a pdf file.

Upgrading old version of Fort hangs, what to do?
Sometimes it might be necessary to uninstall the old version first before installing a new version of Fort.
Does Fort support Linux or OS X?
There are some plans for the Linux version at least.
In what programming language Fort is written in?
It's written in C# against .NET Framework 4 or later.
Can I use Fort to encrypt my whole hard drive?
Fort is not designed for that. Instead, Fort is designed to encrypt individual files. You could take a look at Veracrypt which is designed for disk encryption.
Where is this project based?
Our office is in Finland and all the core developers are citizens of Finland.
Can I send an encrypted file to my friend by email?
Yes. The easiest way for your friend to decrypt the file is to install Fort on his/her computer. Of course, your friend also needs to know the passphrase which was used to encrypt the file. Do not send the passphrase by email! (or if you do, make sure to encrypt the email using PGP.)
I have encrypted a file and I forgot the passphrase or lost my keyfile. Can you help?
Sorry, we can't. There are no backdoors and bruteforcing the passphrase is basically impossible. Your best change is to try to remember the passphrase. Always keep a backup of your keyfile in a safe place.
Does Fort support big files?
Yes. Basically there's no limit how big or small the file can be. Keep in mind that encrypting or decrypting huge files will take a lot of time depending on your computer.
I have important and private files in my Dropbox, can I use Fort to encrypt them?
Yes. If you install the Dropbox software to your computer you can encrypt and decrypt files directly in the Dropbox directory. You should not keep important and private files in Dropbox (or any other similar cloud service) without encrypting them first.
How do I know which files are encrypted?
When you encrypt a file, Fort will change the file association and the icon of the file will change(document with a lock in it). File extension is also changed to .fortenc. To decrypt the file you can simply double click the file.
