2. Initialize the system and enable locking.

The following command assumes you have placed the JSON file in the /tmp directory:

$ sudo nv-disk-encrypt init -f /tmp/<your-file>.json -g

$ sudo nv-disk-encrypt lock

3. When prompted, enter a password for the vault.

Passwords must consist of only upper-case letters, lower-case letters, digits, and/or these

special characters: ~, :, @, %, ^, +, =, _, and ,.

4. For security purposes, delete the JSON file in the temporary location.

5.5.2. Example 2: Generating Random Passwords

This section provides information about how to generate random passwords.

The following command uses the -k and -r options, so you will not be prompted to enter

passwords. After you pass the vault password into the command, the command instructs the

tool to generate random passwords for each drive.

$ sudo nv-disk-encrypt init -k <your-vault-password> -g -r

$ sudo nv-disk-encrypt lock

The vault password must consist of only upper-case letters, lower-case letters, digits, and/or

these special characters: ~, :, @, %, ^, +, =, _, and ,.

5.5.3. Example 3: Specifying Passwords One at a

Time When Prompted

This example provides information about how you can specify passwords one at a time.

If there are a small number of drives or you don’t want to create a JSON file, issue the

following:

$ sudo nv-disk-encrypt init -g

$ sudo nv-disk-encrypt lock

The software prompts you to enter a password for the vault, and then a password for each

eligible SED.

Passwords must consist of only upper-case letters, lower-case letters, digits, and/or these

special characters: ~, :, @, %, ^, +, =, _, and ,.
