Cisco Secret 5 Decrypt [updated] Review

Cisco introduced Type 5 years ago to replace the incredibly weak Type 7 (which is easily reversible using a simple XOR key). At the time, MD5 was considered secure.

I notice you're asking about decrypting Cisco Type 5 passwords. I should clarify a few important points: cisco secret 5 decrypt

If an attacker gains access to your router's startup configuration, they can copy the Type 5 hash and crack it offline. Because MD5 is so fast to compute, even complex passwords can eventually be cracked with enough computing power. Cisco introduced Type 5 years ago to replace

Enter global configuration mode and set the default to Type 9. I should clarify a few important points: If

| Type | Method | Reversible? | |------|--------|--------------| | Type 0 | Cleartext | Yes | | Type 4 (deprecated) | SHA-256 (weak, broken) | No (but collidable) | | Type 5 | MD5-based hash | No (one-way) | | Type 7 | Vigenère cipher (obfuscation) | — easily reversible | | Type 8 | PBKDF2-SHA256 | No | | Type 9 | Scrypt | No |
