Partition creation and encryption via a terminal

Encryption is any technique that scrambles data based on a predictive pattern using an encryption key. The resulting data is unreadable without a special decryption algorithm and a corresponding decryption key (also called a passphrase), calculated precisely for the encryption key.

The keys are mathematical numbers. Encryption is used not only for partitions but also for different internet and network protocols (such as SSH and HTTPS), separate files (such as a 7zip or other archive files, which cannot be opened without the key/password), and others. We will learn more about the internet protocols in Chapter 12.

If you have selected the additional encryption option during installation, you have already seen that your Manjaro installation will not load until the passphrase for its drive partitions is provided. I haven’t advised you to select it, as Linux is already secure enough. Despite this, when we talk about sensitive...
