What is the difference between password protection and encryption? please answer quick, i cant pass this test for the life of me

Answers

Answer:Password protection is like locking something in a safe-deposit. It means no one can get to the locked content without knowing the right combination. This method is used on separate documents, folders, and other data the computer's user may want to protect from other people who might have access to the device. The problem is, if someone interested in such content obtains the password or finds a way to open it without it, the content might be revealed despite the owner's efforts to keep it hidden. Unfortunately, there are a lot of ways hackers could obtain the password or hack in without it. For example, it could be obtained with the help of malware, or it might be guessed if the user chooses a weak password. Not to mention, when it comes to PDF documents, the passwords placed on them can be removed using the CMD window or specific.

Password encryption is a step up from password protection. The term can be a tad confusing because, in fact, you cannot encrypt the password itself. Instead, by setting up "password encryption" you are creating a password AND encrypting the contents of the file. In our example (see instructions below), the contents of the user's PDF document are not only password protected, but also encrypted. It is a process during which the content one wishes to keep secret is altered to make it unrecognizable. For example, if it is a text document, letters of each word might be shuffled with additional characters so the words would no longer make any sense. The reverse process is only available if the person who wants to decrypt this data can provide a specific decryption key or a password. In other words, even if the password is removed no one could read the hidden content as it still would need to be decrypted. Of course, it is important to realize you might be unable to retrieve it too if you lose the decryption key, aka, the password.



PLS MARK ME AS BRAINLIEST.

Password protection restricts access to a resource, while encryption secures the actual content of that resource by transforming it into an unreadable form.

Ask about the difference between password protection and encryption.

Now, Password protection and encryption serve different purposes when it comes to securing data.

Password protection is a method of restricting access to a device, system, or specific files by requiring users to enter a password. It acts as a barrier to prevent unauthorized individuals from accessing the protected resource.

The password is typically a combination of characters that only authorized users should know.

Encryption, on the other hand, is a technique used to convert plain text or data into an unreadable format, called ciphertext, using an encryption algorithm.

The ciphertext can only be decrypted back to its original form by someone possessing the decryption key.

Encryption ensures that even if someone gains unauthorized access to the data, they will not be able to read or understand it without the decryption key

Hence, Both measures are commonly used together to enhance data security.

Answers

The time complexities of the functions is (a) f1 = f3 < f2

How to compare the time complexities?

The code of the functions f1, f2 and f3 are added as an attachment

To compare the time complexities of the functions, we check the loop and conditional statement in each function.

From the attached code, we can see that:

Function f1: 2 loops and 1 conditional statementFunction f2: 2 loops and 1 conditional statement in the second loopFunction f3: 2 loops and 1 conditional statement

In function f2, we have:

The conditional statement in the second loop implies that the conditional statement would be executed several times as long as the loop is valid.

This implies that:

f2 > f1 and f2 > f3

The number of loops and conditional statement in functions f1 and f3 are equal

This means that

f1 = f3

So, we have:

f2 > f1 = f3

Rewrite f2 > f1 = f3 as:

f1 = f3 < f2

Hence, the time complexities of the functions is (a) f1 = f3 < f2
