Thus, every online service or script that claims to "decrypt Cisco Type 5 passwords" is actually a – not a decryption tool.

If you need to prove the password (e.g., migration or auditing), you can extract the hash and run an offline dictionary attack:

# Generate a Cisco Type 5 hash for testing (on Linux with mkpasswd) mkpasswd -m md5 -S cisco mysecretpass # Output: $1$cisco$Tm3fH4jK9lQ8xP2mN7bR/.

While you cannot "decrypt" it, you can it using brute-force or dictionary attacks.
