deps.dev package-file bloom filters
Membership filters over per-file hashes from Google's
deps.dev public BigQuery dataset
(bigquery-public-data.deps_dev_v1) — files inside npm, PyPI, Maven,
Go, NuGet, and Cargo package archives. deps.dev data is CC-BY-4.0
(attribution: Google / deps.dev).
- 172,425,526 keys each: sha1 (UPPERCASE hex) and sha256 (lowercase hex), p = 1e-4, 394 MiB each
- Extracted from the 2026-07-20 snapshot partition via BigQuery free-tier sandbox queries ($0)
- Package-registry coverage evolves; this is a point-in-time extract
Rebuild
EXTRACT.md in this repo documents the exact BigQuery queries and
the free-tier setup (billing-free sandbox project, tabledata.list
download); bq_download.py pulls the result tables, then
./dcso_bloom_build.py depsdev.sha1.bloom sha1 *.sha1.hex (and
likewise sha256).
Format
DCSO bloom filter format (github.com/DCSO/bloom), the same format
CIRCL publishes hashlookup in: 48-byte little-endian u64 header
(version, n, p, k, m, N) followed by the bit array. Keys are hex
digest strings — UPPERCASE for sha1, lowercase for sha256 (the
hashlookup convention). Any DCSO-compatible reader works.
Membership answers are probabilistic: p = 1e-4 false-positive rate, no false negatives. Confirm anything important against the source.
