Answer:
a) Generate a new public and private key
Explanation:
You encrypt a message using the recipient's public key and the recipient decrypts the message using his own private key. Only the public key can be known by an external agent. The private key is for the individual and is not expected to be shared. In the event that the recipient cannot decrypt the message, it is unsafe to send one's private key to him. He does not even need one's private key to decrypt the message, he needs his own private key.
The best thing to do is to generate another means of security by generating new public and private key so that the sender encrypts the message with the new public key and the receiver decrypts it using his new private key.
Option B is wrong because, if the encryption is removed, the aim, which is to secure the message from intruders is not achieved.
Answer: The following code is in c++
#include <iostream>
#include<math.h>
using namespace std;
int main()
{
float a,b,c;
cout<<"Enter height and base of triangle\n";
cin>>a>>b; //reading two sides from user
c=sqrt(pow(a,2)+pow(b,2)); //calculating hypotenuse
cout<<"Length of hypotenuse is "<<c; //printing third side of triangle
return 0;
}
OUTPUT :
Enter height and base of triangle
3
4
Length of hypotenuse is 5
Explanation:
In the above code, three variables a, b and c of int type are declared. After that, it is asked from user to enter the value of a and b. The user puts the value and then c is calculated with the help of Pythagoras theorem formulae which squares the values of two sides and then adds them to calculate hypotenuse of a right angled triangle and finally c is printed to console.
