Generating Hashes

In this activity, you will continue to be a security analyst working for the Hill Valley Police department.

Captain Strickland believes that the Alphabet Bandit, who is likely an insider, has been changing the investigation report files to throw off the investigation.

Fortunately, the Hill Valley Police Department has backup files of all the investigation reports.

Captain Strickland would like you to determine if any investigation report files have been changed, as well as what was changed.

Your task is to generate hashes of each backup and current file and compare the hashes to determine which files were changed.

You must then use command$-$line tools to determine the changes made to those files.

Instructions:

Extract the investigation files provided to you.

Note that there are directories titled current and backup, each of which contain the investigation report files.

It's quite likely that the Alphabet Bandit modified the data in the current files.

Use md$5$sum to generate hashes of all the files into a single file called hashes.

Compare the hashes with a single md$5$sum command to determine which of the files were changed in the current directory.

Use the diff command to figure out what was changed in the modified files.
