# 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.
