Extracted text: Suppose Alice has a public key with modulus 815153 and encryption exponent 91. Eve intercepts a ciphertext 766247 from Bob that was encrypted using this key. She calculates 766247 941 (mod 815153)= 143804 and asks Alice to decrypt this message as an authentication test. Alice responds with the decrypted message 167698 Find the plaintext without factoring Alice's modulus.
