Empreintes et dates d'observation

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.

2.3.23+dfsg.1-1.1+b2 / 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: f2d74897d6d93954a163d023ae0deecd630991a6f52b3d5152b0aae1d206b428

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

printf '%s  %s\n' 'f2d74897d6d93954a163d023ae0deecd630991a6f52b3d5152b0aae1d206b428' 'libqd-dev_2.3.23+dfsg.1-1.1+b2_amd64.deb' | sha256sum --check --strict -

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