MD5 (Message-Digest algorithm 5) is a widely used cryptographic hash function with a 128-bit hash value. As an Internet standard, MD5 has been employed in a wide variety of security applications, and is also commonly used to check the integrity of files. An MD5 hash is typically expressed as a 32-character hexadecimal number.
If you take care of the system integrity and therefor security of your computers, you might have used MD5 in the past. Bottom line - checking the MD5 hash for a file gives you assurance it has not been tampered with.
MD5 Mac OS X application can be used for both checking the hashes for existing files, as well as for creating new hashes for the files located on your computer.
The software works flawlessly, the only thing I would like to see in the new version is support for actual MD5 files that don't have .md5 extension. A number of download sites offer MD5 hashes in files with a format such as software.md5.txt, so this would be a nice addition.
