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.
