HashCalc for Windows

Hash, CRC, and HMAC calculator

HashCalc is a free-of-charge desktop utility that allows you to easily calculate hashes, checksums, and HMAC values for texts, hex strings, and other file types. It presents the 13 most popular hash and checksum algorithms for computation that you can freely choose from. This includes MD2, MD4, MD5, SHA-1, SHA-2 (256, 384, 512), RIPEMD-160, PANAMA, TIGER, ADLER32, and CRC32.  

On top of that, HashCalc also supports MD4-based custom hash data that is commonly used in eDonkey and eMule applications. This cost-free tool can be an excellent alternative to OpenHashTab, HashTab, and GtkHash.

A simple yet powerful solution in computing 

HashCalc is developed more like a local suite rather than online unlike most of its competitors. It is a straightforward companion in calculating or generating a cryptographic checksum for your computer files. It will come in handy especially in times when you need to verify the stability of any downloaded file. Simply by comparing the hash presented on your computer with the one flashed on the developer’s site. 

There are two modes of computation that you can operate here—Hash/Checksum and HMAC. Moreover, the three types of input formats that it supports—files, text strings, and hex strings—empower the tool to work on all types of files available including audios, videos, archives, documents, etc. Although its user interface gives an outdated look nonetheless, it's clear and intuitive enough even for beginners to easily grip with. 

To compute a hash, just choose the ‘File’ format, and utilize the built-in browser to import the specific file you wish to calculate. For files with smaller sizes, you can expect quick and instant results. This useful package is also capable of handling large files of up to 15 GB as tested by the developer but it can take a long while to finish the process.

More straightforward and robust substitute 

HashCalc is undoubtedly an excellent alternative for web-based utilities of the same pack. What makes this a better grab is its ability to be utilized even without an internet connection required. Its user interface appears old but, still highly functional and does its job impressively. Calculating hash, checksum, and HMAC will be a no sweat task when done through this software.
