What is Cisco IOS type 7? How to decode it

Cisco IOS type 7 is a network authentication hash type. It is not a one-way password hash — the original value can be recovered directly without cracking. This page shows how to recognise it and the exact commands to attack it.

All identification runs locally in WebAssembly. The commands below write the hash to a local file on your machine — nothing is sent to this site.

Identifying the hash

The hash identifier on the home page detects Cisco IOS type 7 entirely in your browser — your hash is never uploaded. A typical example looks like this:

044B0A151C36435C0D

Decoding this value

Cisco IOS type 7 is not a cryptographic password hash, so there is nothing to "crack". The original data can be recovered directly:

# Cisco type 7 is a reversible Vigenère cipher — decode with a type-7 tool, e.g.:
echo '044B0A151C36435C0D' | ciscot7 -d
