DCE RSA Public Key Cryptography (*Read Description*)

*Update* C=P^e mod n P=C^d mod n Incorrectly mentioned (p = c^e mod n). Sorry for the mistake. Q) Using RSA algorithm, user X chooses the public key (n=21, e = 5). Compute the private key d of user X. User Y wants to transmit message M=19 to user X in a confidential manner using RSA algorithm, determine the ciphertext C. RSA Public Key Cryptography.
