A package name and version do not prove that the expected file was downloaded. Verification links downloads to trusted artifacts.
Evaluation approach
Establish checksum or signature expectations through a trusted process. Avoid automatically approving unexplained changes.
Application example
Review provenance and publisher when adding verification data for a new release.
Limits and considerations
A hash fetched through the same untrusted channel may provide no independent assurance.
Where should expected hashes come from?
Review the relationship between publication source and file. Automatically promoting an unknown download to the expected value removes the verification boundary.
Checks and decisions
- Identify trust sources
- Stop unexpected changes
- Record approval
