SFV file converter

This tool accepts SFV-formatted input, either as text or an SFV manifest, and parses per-line entries that map a filename to a CRC value. It validates the line structure and normalizes CRC strings to hexadecimal form for downstream processing. The result includes a per-file mapping and a compact summary of the manifest.\n
Conceptually, the converter mirrors the SFV manifest content into one or more target hashes (MD5, SHA1, SHA256, etc.). For each file, it outputs the converted hashes alongside the original filename and the original SFV CRC, enabling side-by-side verification and cross-format compatibility.\n
Audience and value: software distribution teams, QA testers, and data engineers gain faster reconciliation, lower manual effort, and better traceability in release workflows. The tool is designed for batch manifests, large archives, and environments requiring cross-format validation.\n
Core features: input flexibility (text or file), multi-target hash generation, per-file results, summary metrics (total files, valid lines, invalid lines), CSV/JSON export options, and robust error handling. Use cases include software releases, ISO or archive distributions, and automated integrity checks in CI pipelines.
