File hashes, also known as file checksums, are values calculated using a variety of special cryptographic algorithms based on the data contained within the file.
There are numerous hashing algorithms available, including MD5, RIPEMD, SHA-1, Whirlpool, Tiger, and others. These hashes can be used to see if the contents of the files have changed. This is because when the file data changes, so does the calculated file hash.
As you might expect, we require specialized tools to calculate file hashes. File Voyager is a popular and free file manager that can be used to calculate file checksums. It supports a wide range of file hashing algorithms.
Here’s how we can go about it for many many file hashing algorithms. Here is how we can do it:
- Download and install File Voyager
- Launch File Voyager and navigate to the folder containing the files to be hashed. Select all of the files for which hashes should be calculated, and then click the Hash Tool button in the toolbar.
- This will open a new window where we can choose which hashing algorithms we want to use for hashing. CRC16, CRC32, HAVAL, MD2, MD4, MD5, Panama, Ripe MD, Sapphire, SHA-1, SHA-256, SHA-384, SHA-512, Snefru, Square, Tiger, and Whirlpool are among the hash algorithms available. After making your selection, click the Compute Hashes button.
- Another window will appear with all of the details of the files as well as all of their calculated file hashes. All calculated hashes can be saved to a CSV file. You can also select to save only a specific type of hash for all files to the CSV file.
- On a Windows PC, this is a very quick and simple way to calculate file hashes. The File Voyager file manager is more than just calculating and matching file hashes; it also has a plethora of other features. It includes VLC codecs, for example, so you can preview all types of media files directly from the file manager.
