How to use File Integrity Manifest Verifier

Add the requested files or choose a folder.
Review the options and the displayed queue.
Select Verify Manifest, inspect the result, and download the generated JSON or CSV.

What this file tool does

The verifier parses a manifest, locates each expected path, recalculates the listed digest algorithm, and records every outcome.

Match paths, confirm sizes, calculate fresh hashes, and compare normalized digest strings.

A successful check proves agreement with the supplied manifest, not that the manifest itself came from a trusted source.

Supported inputs and limits

The tool works with files exposed through the browser picker. Actual limits depend on available device memory and browser support.

Tips

Keep an untouched copy of important source files.
Review the result list before using the download.
For large batches, test a small sample first.

Frequently asked questions

How do I verify files with a JSON checksum manifest?

Select the manifest together with the target files or folder, then run verification.

What does a hash mismatch mean?

The current file bytes do not match the digest recorded in the manifest.

Can the verifier find missing files?

Yes. Every manifest path without a matching selected file is reported as missing.

Does verification trust file modification dates?

No. Cryptographic hashes are recalculated from the actual bytes.

Can I verify a manifest made by another program?

Only if its JSON fields are compatible with the Callfile manifest structure.
