Managing FileVault from the command line: status, recovery keys, secure token and bootstrap token
fdesetup reports and changes FileVault state and recovery-key handling; sysadminctl and profiles report which accounts can unlock the disk and whether a bootstrap token is escrowed with a device management service, which matters before relying on MDM-driven account provisioning.

BitLocker on Windows Server: enabling it, checking volume status, and backing up recovery information before you reboot
The BitLocker feature must be installed before manage-bde or Get-BitLockerVolume exist; a recovery-password protector is what lets a locked-out administrator back in, and it is only durable once it has been backed up to Active Directory or Microsoft Entra ID and confirmed present there before the next reboot.

Encrypting a data volume with LUKS2: format, open, crypttab, and what a lost header means
cryptsetup luksFormat and luksOpen set up and unlock a LUKS2 volume, and /etc/crypttab makes the unlock happen automatically at boot; a lost passphrase and a lost or damaged LUKS header are both unrecoverable, which is why luksHeaderBackup is a required step, not an optional one.
