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. + +![FinalCrypt][4] + +### 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. + +[FinalCrypt](https://sites.google.com/site/ronuitholland/home/finalcrypt) + +**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?
