v1.2.8Verified publisher

Looks up a file hash in CIRCL hashlookup to see whether it belongs to known software, such as NSRL sets

Community-packaged from github.com/hashlookup/PyHashlookup: the registry's community pins the upstream release; the tool is its authors' work. Maintain that project? Claim this package.

Run

TerminalAgent

Through ot mcp, an agent calls run_tool with this; ot asks you before anything that goes online or touches a target. Set it up: ot mcp install claude (or cursor, vscode, codex, gemini).

{"tool":"osintverse-community/hashlookup","target":"8ED4B4ED952526D89899E723F3488DE4","input_type":"hash"}

Or just say: "Run osintverse-community/hashlookup on 8ED4B4ED952526D89899E723F3488DE4 with OTInstaller." The registry's read-only MCP server at api.otinstaller.com/mcp can find tools without installing anything.

ot run osintverse-community/hashlookup --hash 8ED4B4ED952526D89899E723F3488DE4 --format table

ot install osintverse-community/hashlookup

Python wheel, run in a read-only container (Docker optional with --native) · network allowed · no key · up to 1 min. The first ot run installs the tool after asking once. The example value is the registry's own test input, so this command has run. Drop --format table for JSON.

What this script does

Downloads the latest ot release for your machine from GitHub Releases.
Checks its SHA-256 against checksums.txt, and the Ed25519 signature on that file against the key built into the script.
Puts ot in /usr/local/bin or ~/.local/bin. Nothing else is written. Read the script.

hashlookup (community package)

This repository packages github.com/hashlookup/PyHashlookup for the OTInstaller Registry as osintverse-community/hashlookup. The tool is the work of its authors, under the GPL-3.0 license; this repository only holds the manifest and release workflow.

Report problems with the tool upstream, and problems with the packaging here. If you maintain the upstream project and want to publish it yourself, open an issue or run ot claim osintverse-community/hashlookup: the package is transferred to you.

It installs the upstream project's own release from PyPI, pinned by version and hash; nothing here is rebuilt.

Queries CIRCL's public hashlookup service, which needs no key. A hash it doesn't know prints {"message": "Non existing MD5", ...} and still exits 0.

ot run --native on Windows fails: the CLI builds its URLs with the operating system's path separator. Runs in the container are not affected.

ot run osintverse-community/hashlookup --hash …

Packaged version: 1.2.8.
