Where is LUKS header stored?
The LUKS header stores important information which is needed to decrypt the LUKS device. That includes metadata, the keyslots and the SALT. When using a default LUKS device, the header is stored on the same device as the data area. It is possible to detach the header and therefore store it on a different disk.
Where is Crypttab?
The /etc/crypttab file describes encrypted block devices that are set up during system boot. Empty lines and lines starting with the # character are ignored. Each of the remaining lines describes one encrypted block device, fields on the line are delimited by white space.
Where are the encrypted keys stored in LUKS2?
In this case an encrypted key is stored on disk/removable media, acquired via AF_UNIX, or stored in the LUKS2 JSON token metadata header. The encrypted key is then decrypted by the PKCS#11 token with an RSA key stored on it, and then used to unlock the encrypted volume.
Where is the crypttab key stored in Linux?
In this case an encrypted key is stored on disk/removable media, acquired via AF_UNIX, or stored in the LUKS2 JSON token metadata header. The encrypted key is then decrypted by the PKCS#11 token with an RSA key stored on it, and then used to unlock the encrypted volume.
Where do I Find my crypttab volume keys?
If the field is not present or is ” none ” or ” – “, a key file named after the volume to unlock (i.e. the first column of the line), suffixed with .key is automatically loaded from the /etc/cryptsetup-keys.d/ and /run/cryptsetup-keys.d/ directories, if present. Otherwise, the password has to be manually entered during system boot.
What does the / etc / crypttab file do?
The /etc/crypttab file describes encrypted block devices that are set up during system boot. Empty lines and lines starting with the “#” character are ignored. Each of the remaining lines describes one encrypted block device. Fields are delimited by white space.
