. You can create an empty file with an initial set of attributes by using the createFile(Path, FileAttribute<?>) method.

If you do not specify any attributes, the file is created with default. LUKS, Linux Unified Key Setup, is a standard for hard disk encryption. It standardizes a partition header, as well as the format of the bulk data. LUKS can manage multiple passwords, that can be revoked effectively and that are protected against dictionary attacks with PBKDF2. These are valid LUKS actions: luksFormat <device> [<key file>] initializes a LUKS partition and sets the initial key.
