As applicable for the Operating System on your computer (e.g., macOS, Windows, Linux), find out how to execute MD5; here are some hints:

macOS/Linux: Open a Terminal window. Type MAN MD5 and read the instructions.

Run MD5 using "Message-One" as input

Run MD5 using "Message-Two" as input.

Run MD5 using "Message-Three" as input.

Determine why the three MD5 values are not the same.

In as little space and time possible--in the space below, answer these questions:How many characters did MD5 return for:

Message-One?

Message-Two?

Message-Three?

What were the last four (right-most) characters MD5 returned for:

Message-One?

Message-Two?

Message-Three?

Why the three MD5 values are not the same?

What is the value to you--as an Information Systems Professional working in Large-Scale, Distributed Systems environments--in knowing about MD5 (SHA-1, CRC, or the multitude of other mechanisms used to calculate Checksums)?
