MD5
This program is FREEWARE.
This is our implementation of the famous MD5 algorithm, and presents an easy and highly secure way of verifying the integrity of files. Single-line text, multi-line text and file contents are all supported inputs. The resulting MD5 hash is displayed in a textbox for easy clipboard copying.
Software (including DiamondCS software listed on this site) and various other files are often accompanied by an MD5 checksum, also known as a hash - you can see one for this utility towards the bottom of the page. This serves as a unique identifier for the contents of the file - if the file contents change then so does the MD5 hash, making it easy to verify the integrity of files to ensure they haven't been modified in any way.
A brief description of MD5:
The algorithm takes as input a message of arbitrary length and produces as output a 128 bit (16 byte) "fingerprint" of the input (also known as a "message digest", "checksum" or "hash"). It is conjectured that it is computationally infeasible to produce two messages having the same message digest, or to produce any message having a given prespecified target message digest. The MD5 algorithm was designed by Ron Rivest.
Explorer Right-Click Support:
This utility integrates with Windows Explorer so you can simply right-click on any file, click the 'MD5 Calculate' menu item and the MD5 hash will be calculated, displayed and also selected, allowing you to immediately press Ctrl+C to copy the result to the clipboard.
