I need some help with discrete math!

For what integers n between 0 and 26 does the encryption functionf(p) = np mod 26 have an inverse?

For the RSA encryption system, generate a public and private key using p=7 and q=11.

a. Find a valid RSA key (E, N, D)

b. Encode the message "30" using the public key. Then use the private key to decrypt the coded message and get backthe original message.

Thank you!
