💽 Phantomdrive is an open-source USB drive designed to conceal its actual capacity. Upon initial insertion, the device presents itself as an 8GB disk. To access the secondary partition, a file named "unlock.txt" must be created, followed by the entry of the password; the drive will subsequently unmount and remount, revealing the remaining data. All data is encrypted in place using an AES-256 key derived from the password. This mechanism is fundamentally different from how Veracrypt operates.
