This is a quick and easy method to generate a somewhat random password. This simply generates the MD5 hash for the integer returned by the time() function and then truncates it to the specific length.

This could be used for any type of simple hash checking. It could also be used to store a "password" that had to be verified. This code is completely managed.

Is this file the same as that file? The files may or may not be binary. We could compare the modify dates, or the sizes. But, those are not very accurate to know if a file has really changed.

Introducing MD5 Checksum. We can feed the files into Digest::MD5 in binary mode.

This is a great way to do Incremental Backups.

This is also an easy way to verify checksums when downloading files from the internet which list their MD5 Checksums.

You'll need the Digest::MD5 Perl Module.
