p = 17
q = 13
e = 41
d = 89
What is the public key?

Expert Solution

Step 1

Public and Private keys in the RSA algorithm

The public key is used to encrypt the message that the sender transmits and this key is known to everyone who wants to send messages.
In RSA, the public key is provided with the pair of numbers that are (e, n).
The private key is the secret key that the receiver uses to decrypt the message sent by the sender.
The private key is provided with the pair of integers that are (d, n) in the RSA algorithm.
