## Description

CyberChef performs local data transformation — encoding, decoding, encryption, compression, hashing and parsing — on text the user supplies or selects. 

It presents the user's saved operations in a popup or side panel and the full CyberChef application in an extension tab. All processing happens on the user's device; the extension makes no network requests.
