cksfv is a command-line utility for creating and checking Simple File Verification (.sfv) listings using CRC32 checksums.
It can generate new SFV files from a set of files, validate existing checksum listings against files on disk, and recurse through directory trees when working with larger collections. The tool is intended for integrity checking and compatibility with SFV-based workflows rather than cryptographic security.
This is free and open source software.
Key Features
- Creates .sfv listings from one or more files and writes the checksums to standard output.
- Verifies files against existing .sfv catalogs and reports checksum mismatches or missing files.
- Recursively scans directories to check .sfv files, with optional symlink following during recursion.
- Supports case-insensitive filename matching for verification scenarios involving case-insensitive filesystems.
- Can change to a target path before verification and can restrict checks to selected files.
- Can strip directory names when generating listings so only basenames are stored in the output file.
