SFV Verifier

Verify selected local files against an SFV manifest and report every match, mismatch, missing, duplicate, malformed, and unused entry.

0 / 200,000
0 / 20 files (0 B / 250 MB)

How to use

Paste an SFV manifest and select the corresponding files. Filenames are matched safely; review all statuses rather than treating one matching row as overall success.

Example

Input
Manifest: abc.txt 352441C2; selected abc.txt contains exactly abc
Output
MATCH: abc.txt 352441C2

Limitations

Malformed or duplicate entries prevent an unqualified success. Filenames must match exactly, including case and Unicode code points; case or normalization aliases are reported as mismatches, not silently accepted. CRC-32 detects accidental changes but is not authentication.

Frequently Asked Questions

What happens when a selected file is not in the manifest?

It is reported as unused rather than silently ignored.

Does a matched SFV prove the download is genuine?

No. CRC-32 is not cryptographic authentication; a malicious file and manifest can be changed together.
