Checksum e date di osservazione

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.

0.7.8+ds-1+b2 / arm64Observed 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: 0430db4576a74e8b6e4032d3224d6f3ed98f383456dda2acea39414a8c889f6d

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

printf '%s  %s\n' '0430db4576a74e8b6e4032d3224d6f3ed98f383456dda2acea39414a8c889f6d' 'optipng_0.7.8+ds-1+b2_arm64.deb' | sha256sum --check --strict -

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