Editors' reviewThis freeware utility verifies the integrity of a file by quickly comparing its checksum to a given one, but it lacks expected features. Akkai MD5's overly simple, easy-to-use interface makes it easy to quickly browse for files to validate. Using the program is a mere matter of copying a file's MD5 signature to the Clipboard and comparing it to Akkai MD5's generated checksum. No bells or whistles weigh down this utility. We especially like Akkai MD5's Windows shell integration--a rarity in this type of application. Bear in mind that the program checks individual files and not complete folders. We would have liked an option to save generated MD5 values into text files, but it isn't a necessity. Programmers, software developers, and Webmasters with a need to validate file integrity will want this freeware application.
One of the purposes of MD5 signature is to verify the file integrity. The procedure is simple: the publisher provides the MD5 signature of the file and the user confirms it by calculating the signature again and comparing it to the one provided by the publisher. If the signatures match there is a great possibility the file hasn't been altered since it was published.
