Let n = 523 ·809 = 423107. Let e = 17 be the encryption exponent. Find the decryption exponent d. Is d vulnerable to the low exponent attack? Explain why or why not.

Use the cryptosystem above to encrypt the plaintext 16714 and decrypt the ciphertext 99932.

(Suggestion: a good check on your work is to reverse the encryption or decryption and see if you get the other text back.)

(Note: this is cryptography, so please do it in math way)
