checksum

checksum is a free Windows command-line tool for calculating and validating file checksums. It accepts a file path and returns a checksum for the selected file. This makes it suitable for users who work with command-line tools and need to inspect a file’s MD5, SHA-1, SHA-256, or SHA-512 value.

The file can be supplied with the required file option or as a direct path argument. Users can select the checksum type with the type option, while MD5 is the default when no type is specified. The tool supports both relative and absolute Windows paths.

checksum can also compare a file with an existing signature. The expected signature is supplied with the check option, and the comparison is not case-sensitive. A valid comparison produces an exit code of 0, while an invalid comparison produces a non-zero exit code, allowing the result to be used in command-line workflows.

The program includes help options for displaying its available commands and arguments. As a Windows entry in the download catalog, it fits the command-line utility category rather than a graphical desktop application. MirrorNest provides a direct link to the official release instead of hosting a mirrored copy, so the catalog serves as a reference point for obtaining the free software from its original distribution source.
