Hash Verification
A mechanism that verifies the content integrity of files or dependencies by computing and comparing content hash values. Unlike lock files that only pin version numbers, it can detect cases where content has been substituted.
Timeline (last 90 days)
In traditional software engineering, lock files pin the dependency resolution result (which version gets installed), whereas hash verification pins content (what the content is); the two are different.
Common mitigation measures for supply chain poisoning include hash and signature verification of imported artifacts, maintaining a private image registry within the isolated zone, source-level auditing of third-party dependencies, and provenance tracking of datasets.
Every three days the AILegal system runs a scheduled task that fetches each official source, requires that the numbers and terms in the summary appear in the fetched text, and stores the hash of the version it checked; if the hash changes, the norm is flagged for manual review.
The measurement immutability principle requires that the commands, configurations, and test cases used for review remain frozen between fixing rounds, with only the code under test changing; in engineering terms this can be enforced by hash-verifying the review scripts and mounting the test suite as read-only.
Hash verification can only confirm whether two binaries are identical; it cannot verify whether the binaries themselves are trustworthy.
Hash verification cannot confirm whether a binary itself is trustworthy; when everyone starts from the same compromised source, they will compute identical hash values.
