SFV Ninja (Simple File Verification) is a portable checksum verification utility that supports MD5, SHA-1, SHA-256, SHA-384, and SHA-512 checksum files.
SFV Ninja includes two verification modes; The first mode will verify all files in the list like any other typical SFV application. The second mode is designed to only verify newly added files. This second mode is intended to allow you to update an existing SFV file without verifying all of the files. You can also recursively scan a folder for checksum files and load them all at once and it utilizes relative paths whenever possible when generating checksum files.
SFV Ninja is simple to set up and use allowing you quick access to verification no matter your skill level and it is also light on your machine's resources.
