## Description

**OhMyECH - ECH Indicator** is a Chrome extension that gives users a straightforward visual indicator in the address bar showing whether a site uses Encrypted-Client-Hello (ECH), enhancing privacy and security awareness during web browsing.

ECH is an extension to TLSv1.3 that encrypts the Client-Hello message, preventing middle-men from snooping on the Server Name Indication (SNI) and thus protecting the domain name of the website you are visiting. This extension displays a green or red lock next to the address bar similar to the HTTPS lock, making it easy to see if ECH is in use.

Open source and transparent, the extension's code is available on GitHub, encouraging community trust and contributions. This tool is especially useful for privacy-conscious users and security professionals who want to verify ECH adoption in real-time while browsing.
