HashCheck supports a wide variety of hash algorithms and can even generate checksum files. This program adds a new tab to the Windows Explorer file properties dialog that displays file hashes. Some of these alternatives include: HashCheck Shell Extension

If you are looking for an alternative to Hashtab, there are a few other programs that offer similar functionality. A commercial license is required if you use Hashtab at work.ĭownload HashTab Hashtab Alternatives 2023 Hashtab was free for personal use, for students and for non-profits.

Hashtab was available for free and can be downloaded from the developer’s website. HashTab also provides a drag-and-drop interface that simplifies the process of comparing two files. The program supports a wide variety of hash algorithms, including MD5, SHA1, SHA2, RipeMD, HAVAL and Whirlpool. HashTab was a utility for OS extensions that makes it easy to calculate file hashes and compare them against each other.

RELATED: How to Verify a Linux ISO's Checksum and Confirm It Hasn't Been Tampered With You’ll want to verify the cryptographic signature to ensure the hash file was actually signed by the Linux distribution if you want to be absolutely sure the hash and file weren’t tampered with. They cryptographically sign these hashes to help protect against attackers that might attempt to modify the hashes. That’s why modern Linux distributions often provide more than hashes listed on web pages. An attacker could gain control of a Linux distribution’s website and modify the hashes that appear on it, or an attacker could perform a man-in-the-middle attack and modify the web page in transit if you were accessing the website via HTTP instead of encrypted HTTPS. While hashes can help you confirm a file wasn’t tampered with, there’s still one avenue of attack here. Some Hashes are Cryptographically Signed for Even More Security On Linux, access a Terminal and run one of the following commands to view the hash for a file, depending on which type of hash you want to view: md5sum /path/to/file sha1sum /path/to/file sha256sum /path/to/file Even if someone modifies a very small piece of the input data, the hash will change dramatically. You’ll see that, despite a very minor change in the input data, the resulting hashes are all very different from one another. Now compare the second example in the chart to the third, fourth, and fifth. Often these strings have a fixed length, regardless of the size of the input data. Take a look at the above chart and you’ll see that both “Fox” and “The red fox jumps over the blue dog” yield the same length output.

Hashes are the products of cryptographic algorithms designed to produce a string of characters. How Hashes Work, and How They’re Used for Data Verification You can do this with the commands built into Windows, macOS, and Linux. These seemingly random strings of text allow you to verify files you download aren’t corrupted or tampered with. You’ll sometimes see MD5, SHA-1, or SHA-256 hashes displayed alongside downloads during your internet travels, but not really known what they are.
