+FinalCrypt – An Open Source File Encryption Application
+======
+
+I usually don’t encrypt files – but if I am planning to organize my important documents or credentials, an encryption program would come in handy.
+
+You may be already using a program like [GnuPG][1] that helps you encrypt/decrypt your files on your Linux machine. There is [EncryptPad][2] as well that encrypts your notes.
+
+However, I have come across a new free and open source encryption tool called FinalCrypt. You can check out their recent releases and the source on its [GitHub page][3].
+
+In this article, I will be sharing my experience of using this tool. Do note that I won’t be comparing this with any other program available out there – so if you want a detailed comparison between multiple solutions, let us know in the comments.

+
+### Using FinalCrypt to encrypt files
+
+FinalCrypt uses the [One-Time pad][5] key generation cipher to encrypt files. In other words, it generates an OTP key which you will use for encrypting or decrypting your files.
+
+The key will be completely random as per the size of the key – which you can specify. So, it is impossible to decrypt the file without the key file.
+
+While the OTP key method for encryption/decryption is simple and effective, but managing or securing the key file could be an inconvenience for some.
+
+If you want to use FinalCrypt, you can install the DEB/RPM files from its website. FinalCrypt is also available for Windows and macOS.
+
+Once downloaded, simply double click to [install it from deb][6] or rpm files. You can also build it from the source code if you want.
+
+### FileCrypt in Action
+
+This video shows how to use FinalCrypt:

+
+If you like Linux related videos, please [subscribe to our YouTube channel][7].
+
+Once you have installed FinalCrypt, you’ll find it in your list of installed applications. Launch it from there.
+
+Upon launch, you will observe two sections (split) for the items to encrypt/decrypt and the other to select the OTP file.
+
+![Using FinalCrypt for encrypting files in Linux][8]
+
+First, you will have to generate an OTP key. Here’s how to do that:
+
+![finalcrypt otp][9]
+
+Do note that your file name can be anything – but you need to make sure that the key file size is greater or equal to the file you want to encrypt. I find it absurd but that’s how it is.
+
+![][10]
+
+After you generate the file, select the key on the right-side of the window and then select the files that you want to encrypt on the left-side of the window.
+
+You will find the checksum value, key file size, and valid status highlighted after generating the OTP:
+
+![][11]
+
+After making the selection, you just need to click on “ **Encrypt** ” to encrypt those files and if already encrypted, then “ **Decrypt** ” to decrypt those.
+
+![][12]
+
+You can also use FinalCrypt in command line to automate your encryption job.
+
+#### How do you secure your OTP key?
+
+It is easy to encrypt/decrypt the files you want to protect. But, where should you keep your OTP key?
+
+It is literally useless if you fail to keep your OTP key in a safe storage location.
+
+Well, one of the best ways would be to use a USB stick specifically for the keys you want to store. Just plug it in when you want to decrypt files and its all good.
+
+In addition to that, you may save your key on a [cloud service][13], if you consider it secure enough.
+
+More information about FinalCrypt can be found on its website.

+
+**Wrapping Up**
+
+It might seem a little overwhelming at the beginning but it is actually a simple and user-friendly encryption program available for Linux. There are other programs to [password protect folders][14] as well if you are interested in some additional reading.
+
+What do you think about FinalCrypt? Do you happen to know about something similar which is potentially better? Let us know in the comments and we shall take a look at them!
