Cisco's IOS uses two different types of encryption for passwords - type 5 (MD5) and type 7 (an older, insecure proprietary encryption implementation).
This utility allows you to decrypt Cisco Type 7 password strings. They will normally appear in the IOS config as:
username admin password 7 046E1803362E595C260E0B240619050A2D
Enter your Type 7 password string below and click the Decrypt button to display the plaintext:
