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.

Following are the program to calculate even digits sum:
<h3>Program:</h3>
#include <iostream>//header file
using namespace std;
int main()//main method
{
int a[10],s=0,i;//defining an array and an integer variable
cout<<"Enter array values: ";//print message
for(i=0;i<=9;i++)//defining a loop that input array value
{
cin>>a[i];//input array value
}
for(int i=0;i<=9;i++)//defining loop that check array value
{
if(a[i]%2==0)//defining if block that checks even number condition value
{
s=s+a[i];//adding even number value
}
}
cout<<"The sum of even number is: "<<s;//print even number sum value
return 0;
}
Program Explanation:
- Defining a header file.
- Defining the main method.
- Inside the main method, an integer array "a", and two integer variable "s,i" is declared.
- In the next step, a for loop is declared that input the array value, and after input value another loop is declared that check even number value in array.
- In this loop it adds array value and after adding the value a print method is declared that prints its value.
Output:
