This small freeware utility quickly generates MD5 checksums to check the integrity of files, but zipped directories are beyond its scope. SecureMD5's simple, user-friendly interface makes it easy to browse for files to generate their MD5 checksums and verify their validity. SecureMD5 doesn't need a help file; running this program is simply a matter of pointing to the file you wish to validate. It takes only a millisecond to compute the MD5 signature of a file. Users must copy the generated checksum values to the text boxes just below the interface, making the program more complex than it needs to be. From there, you can compare to see whether the values match or not. Unfortunately, this tool doesn't work with folders or zipped directories. SecureMD5 is a great tool for software developers and programmers who often need to validate file integrity.
