1. OBJECTIVE
In this lab, you will simulate performing a message transmission from an origin point to the receiver, aiming to guarantee the integrity of the message without any interceptions.
At the end of this experiment, you should be able to:
recognize hashing algorithms;
identify the basic operation of sending encrypted messages securely from source to destination;
implement the guidelines of a hashing algorithm.
2. WHERE ARE THESE CONCEPTS USED?
Hash algorithms are widely used to verify the integrity of messages to the receiver. They are capable of transforming an input string of any length into a fixed-length character set. This allows you to summarize data, check the integrity of files on shared networks, and also recover passwords stored in databases.
3. THE EXPERIMENT
You must simulate the transmission of messages between a sender and a receiver without interception. For this, the information to be transmitted will be summarized using a hash algorithm, which will be compared with the summary generated at the receiver using the same algorithm.
4. SECURITY
In this practice, there are no risks. You just have to make sure you don't have malicious software installed on your computer or browser. Therefore, it is recommended to use some up-to-date antivirus.
5. SCENARIO
In this practice, you will use a computer with any operating system, requiring only a properly updated web browser.
