Why each option
WPA2 Personal with AES (CCMP) encryption provides extremely strong security that makes practical cracking computationally infeasible, even with modern tools and hardware.
The difficulty is not due to outdated tools, as even the most current and capable tools like Hashcat or Aircrack-ng face the same fundamental cryptographic barrier imposed by WPA2-AES.
While password complexity does increase cracking difficulty, the question attributes the protection to the encryption method (WPA2-AES), not password length alone, and a weak password would still be hard to crack due to the strong key derivation function.
WPA2 with AES-CCMP encryption uses a 128-bit key derived through the 4-way handshake and PBKDF2 with 4096 iterations of HMAC-SHA1, making brute-force attacks computationally infeasible within any practical timeframe. While theoretically not 'uncrackable' in an absolute sense, AES-256/128 has no known practical vulnerabilities, and the key derivation process is intentionally slow to resist offline dictionary and brute-force attacks. For the purposes of this scenario, WPA2-AES is considered cryptographically robust and effectively uncrackable with current technology.
MAC address filtering is a separate network access control mechanism and does not affect the ability to capture Wi-Fi handshakes or attempt offline password cracking, making it irrelevant to the encryption challenge described.
