At hashdd's core is pyhashdd, a killer Python library for profiling files and building hash databases. You can use pyhashdd as a command line tool or a python import to make your own hashdd, or query our API.
Our Bloom Filters allow of super fast offline lookups and are built using popular open source libraries. This enables you to include hashdd data in your own applications!
