Prüfsummen und Beobachtungsdaten

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.

4.3.1-1 / 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: a269f4b6559d394e094ceefc5b5e72a1f1e9b909ad201cd9a725ef44e2fb4ded

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

printf '%s  %s\n' 'a269f4b6559d394e094ceefc5b5e72a1f1e9b909ad201cd9a725ef44e2fb4ded' 'libcoap3_4.3.1-1_amd64.deb' | sha256sum --check --strict -

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