fscrypt

1. fscrypt is a command-line tool available in Linux systems that is used for managing filesystem-level encryption.
2. It provides a simplified interface for managing encryption on the filesystem, with a focus on ease of use for end-users.
3. fscrypt supports a variety of encryption modes, including AES-256-XTS for block encryption and AES-256-GCM for authenticated encryption.
4. It allows users to encrypt specific files or directories on their filesystem, providing an additional layer of security for sensitive data.
5. The tool integrates with the Linux kernel's filesystem encryption framework, ensuring compatibility and reliability across different distributions.
6. fscrypt uses user-space key management, meaning encryption keys are stored and managed by the user, rather than by the kernel.
7. It supports multiple authentication methods, including password-based, key-based, or hardware-backed authentication.
8. The tool offers options for managing encryption policies, such as specifying the default encryption mode for new files and directories.
9. fscrypt provides a convenient option to remove encryption from files or directories, allowing users to easily revert the encryption if needed.
10. It has a well-documented usage guide and command-line interface, making it accessible for both experienced users and those new to filesystem encryption.
