Algorithms We Support
Goodies
pyhashdd
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.
Bloom Filters
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!
Query the API
Use our API for enrichment and quick Good/Unknown determination on hashes. You can find the details of our endpoints in the API Swagger Documentation.
Hash known level lookup with curl
The /v1/knownlevel/<hash> endpoint provides simple, Good/Unknown determinations on hashes.
curl https://api.hashdd.com/v1/knownlevel/838DE99E82C5B9753BAC96D82C1A8DCB
{"result": "SUCCESS", "message": null, "hash": "838DE99E82C5B9753BAC96D82C1A8DCB", "knownlevel": "Good"}
NSRL RDS lookup with curl
Most endpoints also have an NSRL RDS-only companion. For instance, to lookup only NSRL RDS known levels, query the /v1/knownlevel/nsrl/<hash> endpoint.
curl https://api.hashdd.com/v1/knownlevel/nsrl/838DE99E82C5B9753BAC96D82C1A8DCB
{"result": "SUCCESS", "message": null, "hash": "838DE99E82C5B9753BAC96D82C1A8DCB", "knownlevel": "Good"}
Detail lookup with curl
Our /v1/detail/<hash> endpoint provides filenames, products, version, and other details about a hash.
curl https://api.hashdd.com/v1/detail/0000095897E650E4C352EF29EA027713
{ "result": "SUCCESS",
"message": null,
