This article mainly explains "how to use FinalCrypt to encrypt files". Interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let's take you to learn "How to use FinalCrypt to encrypt files"!

FinalCrypt uses a one-time password to generate a password to encrypt files. In other words, it generates an OTP key that you will use to encrypt or decrypt your files.

Depending on the key size you specify, the key is completely random. Therefore, the file cannot be decrypted without the key file.

While OTP keys are simple and effective for encryption/decryption, managing or protecting key files may be inconvenient for some people.

If you want to use FinalCrypt, you can download the DEB/RPM file from its website. FinalCrypt is also available for Windows and macOS.

Download FinalCrypt

Once downloaded, simply double-click the deb or rpm file to install. You can also compile from source if you want.

After installing FinalCrypt, you will find it in the list of installed apps. Start it from here.

After startup, you will see two columns, one for encryption/decryption and one for OTP file selection.

Using FinalCrypt for encrypting files in Linux

First, you must generate an OTP key. Here's how:

finalcrypt otp

Note that your file name can be anything-but you need to make sure that the size of the key file is greater than or equal to the file you want to encrypt. I think it's ridiculous, but it's true.

Once the file is generated, select the key on the right side of the window and select the file to encrypt on the left side of the window.

Once the OTP is generated, you will see the highlighted checksum, key file size, and validity status:

Once selected, you simply need to click "Encrypt" to encrypt the files, and if encrypted, click "Decrypt" to decrypt the files.

You can also use FinalCrypt from the command line to automate cryptographic jobs.

How do you protect your OTP key?

Encrypting/decrypting files you want to protect is easy. But where should you save your OTP key?

If you fail to keep your OTP key in a safe place, it is almost useless.

Well, one of the *** ways is to use a dedicated USB stick to save your keys. You just need to insert it when decrypting the file.

Besides, if you think it's secure enough, you can keep your keys in the cloud.

At this point, I believe that everyone has a deeper understanding of "how to use FinalCrypt encryption files", so let's actually operate it! Here is the website, more related content can enter the relevant channels for inquiry, pay attention to us, continue to learn!
