Yes , it’s true. In a known-plaintext attack (kpa), the cryptanalyst can only view a small portion of encrypted data, and he or she has no control over what that data might be.
The attacker also has access to one or more pairs of plaintext/ciphertext in a Known Plaintext Attack (KPA). Specifically, consider the scenario where key and plaintext were used to derive the ciphertext (either of which the attacker is trying to find). The attacker is also aware of what are the locations of the output from key encrypting. That is, the assailant is aware of a pair. They might be familiar with further pairings (obtained with the same key).
A straightforward illustration would be if the unencrypted messages had a set expiration date after which they would become publicly available. such as the location of a planned public event. The coordinates are encrypted and kept secret prior to the event. But when the incident occurs, the attacker has discovered the value of the coordinates /plaintext while the coordinates were decrypted (without knowing the key).
In general, a cipher is easier to break the more plaintext/ciphertext pairs that are known.

Answer:
Quick analysis tool.
Explanation:
Excel is a spreadsheet application package found in the Microsoft office suite. it's environment on the display screen is called a worksheet and a collection of the worksheets is called a workbook. The excel packet is used for data analysis and interpretation and presentation.
When a group of cells in a worksheet is selected, a small tool kit appears that the lower right corner, it is known as a quick analysis tool. It is use for easy and fast analysis and formatting of that selected group.
Answer:
Explanation:
The following is written in C and creates a structure declaration named savingsAccount and adds all of the values into it as defined in the question.
struct savingsAccount {
char AccountNumber[] = "";
double AccountBalance;
double InterestRate;
double AverageMonthlyBalance;
}
<u>Explanation:</u>
Remember, an algorithm in simple words means a set of instructions or steps to be followed in other to solve a problem.
Note, to decide which commute is cheaper, it means the output of the algorithm should be the cheaper way to commute.
Using pseudocode do the following;
- determine the inputs and outputs of the problem
- arrange the identified problem into micro-tasks
- describe each micro-tasks in the pseudocode
- Test the pseudocode by solving the problem.
