RSA Challenge Two: RSA Small Plaintext and Encryption Exponent AttackThe Problem: Given an RSA ciphertext encrypting a small message with a small public key (e.g. e = 3), recover the message. Malland sent another message to Horridland; however, this time, you don't really know what they might be saying. You do, however, know that the encryption exponent is e = 3, and that Mallanders tend to be very brief and to the point, so you think the message in question is probably very short. Use this knowledge to figure out what the message is. For this exercise, use the following values:
