Versions, suites, and repositories

Each row is recorded package-index metadata for one version, architecture, suite, and repository. Names, URLs, and sizes are source-reported; a link is a potentially mutable retrieval location, not an OpenFactory redistribution claim or proof that OpenFactory retained the artifact bytes.

Checksums and observation dates

For an APT source, signature verification authenticates the repository metadata chain and the Packages index containing this source-reported artifact digest. It does not certify package safety.

4.2.1-3+b1 / amd64Observed Sep 1, 2026 to Sep 1, 2026

Verification status: Metadata observed; artifact bytes were not independently fetched or hashed by this catalog import. The digest below is source-reported.

Source-reported sha256: fb4bcfdc1bbcd2ea479b96955744ffa7a7ea834d7cf8b4ff9a0c442451b74178

After downloading that exact artifact, compare its bytes with the source-reported expected digest:

printf '%s  %s\n' 'fb4bcfdc1bbcd2ea479b96955744ffa7a7ea834d7cf8b4ff9a0c442451b74178' 'libczmq-dev_4.2.1-3+b1_amd64.deb' | sha256sum --check --strict -

A match establishes equality with the repository metadata value. It does not establish safety or catalog-side artifact retrieval.
