This is hdb, a hash database (hdb32) multitool. The hdb package provides a single, multipurpose utility used to generate, query, analyze, and operate on hash database files in the hdb(5) file format. -Say what? An hdb database is implemented as a partitioned hash table. It provides a set of mappings for record keys to record values, where both keys and values are any arbitrary strings of bytes. An hdb file is specifically designed as a "write-once, read-many" (worm) datastore. It is generally used by applications requiring fast read access to "constant" data, that is, data that don't change too much (you define "too much"). The hdb(5) file format is modeled after the cdb(5) constant database specification by Daniel J. Bernstein, but with different internals and enhanced capabilities. -So? The hdb utility provides a single, efficient, and easy to use utility for working with hdb files. It provides a complete set of database functions at the command line, including basic set operations. Generating an hdb database is on the order of 100x faster when compared to building a Berkeley DB or GNU DBM hash database. The hdb file format is also slightly smaller, faster, and better-suited to modern environments when compared to the cdb format. -You wish! Sigh...
