| # Binary package checksums (Debian, Ubuntu, Kali) |
|
|
| Per-artifact checksums of **binary packages (.deb/.udeb) as shipped**, |
| harvested from the distros' own apt `Packages` indexes. Every row |
| carries the pool path, so the claim URL is constructible: archive |
| base + `Filename`. Digest coverage varies by distro — each row is a |
| single witness carrying every digest its index states: |
|
|
| - **debian** — trixie, trixie-updates, trixie-security, sid (all four |
| components + debian-installer udeb sub-indexes): md5 + sha256, plus the debian-installer images tree (initrds, kernels — SHA256SUMS per versioned release) |
| - **ubuntu** — **every release ever indexed with SHA256** (gutsy 2007 |
| → resolute 26.04, plus regenerated -updates/-security indexes back |
| to warty 2004): release + -updates + -security pockets, all four |
| components (main, restricted, universe, multiverse), enumerated |
| from archive.ubuntu.com (supported) and old-releases.ubuntu.com |
| (EOL — pool included, so claim URLs stay live for dead releases): |
| md5 + sha1 + sha256 + **sha512** — 4-hash single-witness rows |
| - **kali** — kali-rolling: md5 + sha1 + sha256 |
|
|
| **2,890,481 rows** across 129 witnesses (debian 152,570 / ubuntu |
| 2,665,512 / kali 72,399), architecture amd64 (arch:all packages |
| included), harvested 2026-08-14. |
|
|
| ## Layout |
|
|
| - `data/debs.parquet` — witness, sha256, sha1, md5, sha512, name, |
| version, arch, filename; **sorted by sha256**. `filename` is the |
| pool path relative to the archive root (`deb.debian.org/debian`, |
| `security.debian.org/debian-security`, `archive.ubuntu.com/ubuntu`, |
| `old-releases.ubuntu.com/ubuntu` for EOL Ubuntu codenames, or |
| `http.kali.org/kali`, by witness). |
| - `maps/sha1.parquet` — sha1 → sha256 (ubuntu/kali rows), **sorted by |
| sha1**. |
| - `maps/md5.parquet` — md5 → sha256 (all witnesses), **sorted by md5**. |
| - `debs.sha256.bloom` — DCSO-format membership filter over the |
| 1,675,146 distinct sha256 keys (p = 10⁻⁴, lowercase-hex keys). |
| `hdx filters fetch debs` installs it so `hdx scan` can route |
| matching files to this dataset. |
| - `debs.tsv.gz` — the normalized harvest the parquet is built from. |
|
|
| Both parquet files carry page indexes (zstd, no dictionaries, |
| 128 KiB pages), so a point lookup over HTTP range reads fetches a few |
| tens of KB. This is how [hashdex](https://github.com/davidar/hashdex) |
| resolves hashes from the CLI and from a static browser page — and how |
| `hdx recipe` attaches fetchable claim URLs to the pool debs inside a |
| Debian install image (a verified, generalized jigdo). |
|
|
| ## Rebuild |
|
|
| `tools/deb_packages.py` (index GETs only, never content) then |
| `tools/debs_parquet.py`, both in this repo and in the hashdex GitHub |
| repo. Suites are a point-in-time snapshot; re-harvest refreshes them. |
