FileHash

Hash codes identify an amount of data in a unique manner. They are unrepeatable sequences of letters and numbers that are generated for any file or text string, allowing computer users to easily verify the data integrity. The digital world does not lack hash checkers, be them online or offline, most offering a standard feature set. FileHash is one of them, a hash checker and checksum comparison tool for Windows.

FileHash runs exclusively in the command console, as no standard GUI is available. This makes it perfect for quick deployment and automation tasks.   The syntax is not difficult at all but it is advisable you take the time to browse through the help and get a glimpse at the used arguments.

With FileHash, you can read the hash codes of any file or text string. The application comes with support for several hash codes, some of the most popular being MD5, SHA1, SHA2, SHA3, Blake2, or Blake3. It can generate both cryptographic and non-cryptographic hashes for individual files, but note that it can also run batch operations, scanning and extracting the checksum for all the files in a folder of your choice. The output can be displayed in the command console, but you can also specify a text file to write the result to.

Aside from reading the hash code and displaying it, FileHash can also compare two hash codes to check the integrity of a file and make sure it has not been tampered with. Evidently, checksums also tell you about errors that might have occurred during data transfers, for instance. You can select two files and let FileHash compare their hashes to check if they match.

There are various other handy options in FileHash. For instance, it allows you to create exclusion lists and filter files in the target location by size.

FileHash is a checksum verifier and a hash generator as well, allowing you to check the integrity of a file with ease. While it runs in the command console only, its syntax is simple and it comes with several usage examples that allow you to quickly learn how it actually works.
