What is File Hash Verifier?
File Hash Verifier is an Openclaw Skills utility for computing and validating SHA-256 checksums so you can confirm that a file is unchanged, trustworthy, and transfer-safe.
It is built for security-conscious developers, DevOps teams, and release managers who need fast, repeatable integrity checks from the command line. With Openclaw Skills, you can compare vendor-published hashes, generate SHA256SUMS manifests for larger file sets, and standardize verification across local workflows and deployment pipelines.
File Hash Verifier Use Cases
- Confirm downloaded ISOs, archives, or binaries were not corrupted or tampered with during transfer.
- Validate deployment artifacts between build and deploy stages in CI/CD.
- Compare a local file against a vendor-published checksum before installation.
- Generate SHA256SUMS manifests for bulk verification in Pro workflows.
- Monitor critical directories for unauthorized file changes with real-time alerts in Pro.
How File Hash Verifier Works
- Provide the file path you want to validate and, optionally, a trusted SHA-256 checksum.
- The skill computes the file's SHA-256 digest locally using the required shell tooling.
- It compares the computed hash against the expected or vendor-published value.
- It returns a pass/fail integrity result and highlights any mismatch for investigation.
- For bulk workflows, it can generate SHA256SUMS manifests for multiple files.
- In Pro workflows, it can watch directories and alert when files change unexpectedly.
File Hash Verifier Setup
- Ensure the required binaries are available on your system.
bash --version
curl --version
There is no additional package installation step in the skill manifest; load the skill and run it directly through Openclaw Skills.
Verify a file against a trusted SHA-256 checksum.
file-hash-verifier verify --file ./downloaded.iso --expected abc123...
- For repeatable release workflows, store the vendor checksum in CI variables, release notes, or a deployment script so the verification step can be automated.
File Hash Verifier Data Schema & Taxonomy
Openclaw Skills keeps the data model intentionally lightweight and CLI-friendly.
