RECOMMENDATIONS
---------------
EOF

cat >> "$summary_file" << EOF
❌ NO VALID HANDSHAKES FOUND
- None of the capture files contain valid WPA/WPA2 handshakes
- Recapture is required before cracking can proceed
- Ensure you capture the 4-way handshake or PMKID
EOF

⚠️ PARTIAL HANDSHAKES FOUND
- $valid_files out of $total_files files contain handshakes
- Consider recapturing missing handshakes
- Proceed with cracking for files that have handshakes
EOF
else

✅ ALL FILES HAVE VALID HANDSHAKES
- All $total_files files contain handshakes
- Ready for cracking
- Total handshake material: $total_handshakes EAPOL pairs, $total_pmkids PMKIDs
