| Type | Algorithm | Reversible? | Security | |------|-----------|-------------|----------| | Type 0 | Plaintext | Yes | None (avoid) | | Type 4 | Custom SHA-256 | No (but broken) | Deprecated/Insecure | | Type 5 | MD5-based hash (salt + 1000 iterations) | No | Moderate (legacy) | | Type 8 | PBKDF2-SHA-256 | No | Strong (recommended) | | Type 9 | SCRYPT | No | Strongest (modern) |

has been the standard for over two decades. It uses MD5 with a salt and 1000 iterations of the hash function. Iterations make brute-force slower, but MD5 is no longer considered secure for high-stakes environments. show running-config | include secret Then copy the $1$

This article will explain, once and for all, what Type 5 secrets really are, why you cannot decrypt them (in the traditional sense), what tools exist to crack them, and the legitimate methods for password recovery on Cisco devices. Before diving into Type 5, let’s clarify the different Cisco password types. Cisco has evolved its password storage over decades.

was introduced as an improvement but was quickly found to be vulnerable due to a weak implementation. It is now deprecated. Iterations make brute-force slower, but MD5 is no
