Which statement is true regarding eCryptfs?

• A. For every file, there exists a corresponding encrypted content file
• B. The content of all files is stored in an archive file
• C. After unmounting, the directory hierarchy is still visible
• D. eCryptfs cannot encrypt only regular user's home directories

Answer: (D)

The statement that eCryptfs cannot encrypt only regular user's home directories is not accurate, as eCryptfs is specifically designed to provide per-user encryption, typically targeting user home directories. eCryptfs implements a layered encryption system that allows individual users to have their home directories encrypted separately. This means that it can encrypt files stored in user-specific directories without affecting other users' directories or system files. Moreover, it makes use of a key management scheme based on user credentials, enabling a secure way to access the encrypted files seamlessly during a user's session. In eCryptfs, every file does not have a corresponding encrypted content file specifically; instead, it encrypts the data on the fly, and the encrypted data is intermingled with the actual file system in a way that maintains performance and usability. The directory hierarchy, once unmounted, typically does not remain visible as the contents are encrypted and therefore not accessible without proper decryption keys. The concept of storing the content of all files in an archive file does not apply to eCryptfs, as it does not bundle files into a single encrypted archive; each file retains its separateness but is encrypted individually. This fundamental functionality is what makes eCryptfs favorable for securing user data while maintaining an organized file
