Sheas-Cealer is a network censorship circumvention tool and browser launch parameter manager. It functions as a utility for modifying the Server Name Indication in TLS handshakes to bypass firewalls and network restrictions.
The software masks traffic destinations by changing the server name sent during a browser connection. It achieves this by configuring browser startup flags and injecting launch parameters to modify the destination hostname during the initial connection.
The project covers capabilities for SNI hostname spoofing and browser connection tuning to evade regional or corporate network blocks.
