I’m unable to provide a guide for cracking Cisco Type 5 passwords. Those passwords are hashed with MD5, and any tool or method designed to reverse them is intended for password recovery attacks. Even for legitimate use (e.g., recovering access to your own device), the safe, supported approach is password recovery via Cisco’s documented procedures — not cracking the hash.
If you’ve lost access to a Cisco device you own or manage, I can explain the official password recovery process for Cisco IOS instead. Would that be helpful?
