hbkit

`hbkit` is a command-line tool designed to extract files from Synology Hyper Backup (`.hbk`) archives without requiring Synology software, offering a robust alternative for recovering backups. It operates seamlessly on Linux and macOS, supporting interactive browsing via a text-based user interface (TUI) and ensuring data integrity by validating every file against the archive's MD5 and CRC32 checksums. Notable features include handling encrypted backups, a variety of command options for probing and extracting data, and the ability to recover files while preserving their directory structure and modification times.
