Alice uses RSA with n = 27046456501 and e = 3. Her ciphertext is c = 1860867. Eve notices that c¹⁴ ≡ 1 (mod n). What does this observation imply about the encryption process?
1) The encryption process is secure
2) The encryption process is not secure
3) The encryption process is reversible
4) The encryption process is irreversible
