LOW

Why flagged The source is hosted on an AWS S3 bucket named 'cryptlib-release', which appears to be the official distribution channel for cryptlib by Peter Gutmann (the project's homepage at cs.auckland.ac.nz links to this distribution method). The checksum is present and non-SKIP (sha256sums has a real hash: 9ef71f0479a71508cfb51f403f7a42dcd5040c31c5f7aebc6bcb178bbfaf8c43), so integrity is verified. The S3 bucket name 'cryptlib-release' is consistent with an official release bucket rather than a personal or random host. The PKGBUILD builds from source using make, installs a shared library, and follows standard patterns. The noextract+manual unzip with -a flag is needed because cryptlib ships a zip-within-zip structure. No binaries are executed from untrusted sources without verification. The cheaper model's concern about a 'SKIP'd checksum' was factually incorrect — a real SHA256 hash is provided. This is a legitimate, if slightly unusual, distribution pattern for this specific project.

LOW AI review downgraded a static finding llm_review

The static rules flagged this MEDIUM, but an AI model (anthropic/claude-4.6-sonnet-20260217) reviewed the full PKGBUILD and judged it LOW (confidence 82%): The source is hosted on an AWS S3 bucket named 'cryptlib-release', which appears to be the official distribution channel for cryptlib by Peter Gutmann (the project's homepage at cs.auckland.ac.nz links to this distribution method).
