By default, the option to encrypt the file system is unchecked during the installation. If you select the option to encrypt your hard drive, you will be prompted for a passphrase that will be asked every time you boot the computer. This passphrase "unlocks" the bulk encryption key that is used to decrypt your partition. If you choose to modify the default partition table you can choose which partitions you want to encrypt.
This is set in the partition table settings. Note that the installation program, Anaconda , uses by default XTS mode aes-xts-plain The default key size for LUKS is bits. Ciphers that are available are:. Manually Encrypting Directories. Following this procedure will remove all data on the partition that you are encrypting.
You WILL lose all your information! Make sure you backup your data to an external source before beginning this procedure! Enter runlevel 1 by typing the following at a shell prompt as root:. This command proceeds at the sequential write speed of your device and may take some time to complete.
It is an important step to ensure no unencrypted data is left on a used device, and to obfuscate the parts of the device that contain encrypted data as opposed to just random data. You now have an encrypted partition for all of your data to safely rest while the computer is off. Add a New Passphrase to an Existing Device. After being prompted for any one of the existing passprases for authentication, you will be prompted to enter the new passphrase.
Remove a Passphrase from an Existing Device. You will be prompted for the passphrase you want to remove and then for any one of the remaining passphrases for authentication.
Creating Encrypted Block Devices in Anaconda. You can create encrypted devices during system installation. This allows you to easily configure a system with encrypted partitions.
To enable block device encryption, check the Encrypt System check box when selecting automatic partitioning or the Encrypt check box when creating an individual partition, software RAID array, or logical volume.
After you finish partitioning, you will be prompted for an encryption passphrase. This passphrase will be required to access the encrypted devices. If you have pre-existing LUKS devices and provided correct passphrases for them earlier in the install process the passphrase entry dialog will also contain a check box. Checking this check box indicates that you would like the new passphrase to be added to an available slot in each of the pre-existing encrypted block devices.
Checking the Encrypt System check box on the Automatic Partitioning screen and then choosing Create custom layout does not cause any block devices to be encrypted automatically.
You can use kickstart to set a separate passphrase for each new encrypted block device. Additional Resources. LUKS home page. Creating GPG Keys. GPG is used to identify yourself and authenticate your communications, including those with people you do not know. In other words, GPG allows someone to be reasonably certain that communications signed by you actually are from you. GPG is useful because it helps prevent third parties from altering code or intercepting conversations and altering the message.
Install the Seahorse utility, which makes GPG key management easier:. Then click Continue. Type your full name, email address, and an optional comment describing who you are for example: John C. Smith, jsmith example. Click Create. A dialog is displayed asking for a passphrase for the key. Choose a strong passphrase but also easy to remember. Click OK and the key is created. If you forget your passphrase, you will not be able to decrypt the data.
You should make a backup of your private key and store it somewhere secure. If you have never used KGpg before, the program walks you through the process of creating your own GPG keypair. A dialog box appears prompting you to create a new key pair.
Enter your name, email address, and an optional comment. You can also choose an expiration time for your key, as well as the key strength number of bits and algorithms. Enter your passphrase in the next dialog box. Publisher: 1Password Verified account. Publisher: Visual Studio Code Verified account. Publisher: KDE Verified account.

At the time of writing, you can choose between the following when creating a new encrypted volume:.
There are 32 and 64 bit versions available, so choose the correct one depending on your system. If you are unsure run:. The official website does not provide links for specific installations, seeming to force you to choose your version through a. At the time of writing, to download the bit console only version, run:.
Check that 7. Simply change the x64 to x32 in the command to download the bit version. Again substituting the version number and architecture type if necessary. Enter 1 , and then press Enter to read the terms and conditions. Hold down your Space key for a while, if, like most people, you are not actually intent on reading them. Enter will also work, but Space goes page by page instead of line by line. Type y to accept the terms, and then press Enter. Press Enter to exit the installer.
TrueCrypt is now installed on your system. You can use any file extension that you want or omit it. A Hidden volume is in essence two TrueCrypt volumes inside each other.
These are very useful if someone uses physical force or blackmail to make you open a TrueCrypt volume or give them your password. With a hidden volume, you can pretend to comply, while in reality only giving them access to the outer volume. This is unlikely to be an issue for the average user.
