The file is a extract file, so you will need to "Extract All" to anywhere.

This file MD5DEEP contains many different kind of hashing algorithms like MD5, SHA1, SHA256 and Whirlpool. Hashing is consider the most basic type of cryptographic, it protects your information from being edited or stolen from non-authorize people. When user A sends the letter "ABC" to user B it will be hashed before transmitted. If there's a middle man who intercept and edit the message, the hash will then be changed to a different type. When user B compare the hash with the originally, user B will notice that it have been edited. In this project, i will create a message and check the hash then, edit of the message to see if the hash actually change.

In order to continue with the hands-on, MD5 message is 128 bits so a short message will actually be a long code, MD5 is commonly used by LINUX operating system. SHA1 creates 160bits while SHA256 creates 256bits as stated by the name. Whirlpool creates hash at 512bits, which will be very long code, giving it higher end security to prevent those attackers.
