Cisco Password 5 Cracker — [best]

First, you need to obtain the hashed password from the Cisco device. This can be found in the device's configuration file.

Cisco recommend migrating away from Type 5 wherever hardware supports newer, more computationally expensive algorithms. Password Type Algorithm Security Status Type 7 Vigenère (Obfuscation) Unsafe (Instantly reversible) Type 5 Salted MD5 Legacy (Vulnerable to GPU cracking) Type 8 SHA-256 (PBKDF2) Strong (Recommended) Type 9 Scrypt Strongest (Memory-hard; highly resistant) For those managing legacy systems, the best defense is using long, complex passphrases and migrating to cisco password 5 cracker

When you see a configuration line like: username admin privilege 15 secret 5 $1$XwAo$7hR9Z/N7S.9Y9j7tO6R4K0 First, you need to obtain the hashed password
