Shadowrocket HTTPS Decryption & Scripting: CA Certificate Trust & In-App Ad Elimination

Master HTTPS decryption (MitM) and JavaScript script rewrites in iOS Shadowrocket. Step-by-step instructions for generating local CA root certificates, enabling full SSL trust in iOS settings, and stripping telemetry trackers.


Key Takeaway (TL;DR): Since modern mobile traffic is encrypted via TLS, domain-level rules cannot filter payload ads or inspect in-app telemetry. Shadowrocket supports local Man-in-the-Middle (MitM) decryption. By generating a private local CA certificate and enabling full trust under iOS Certificate Trust Settings, users can run JavaScript script rewrites to remove mobile video advertisements safely.


1. MitM Security Best Practices

Always generate the Root CA certificate directly on your local device—never trust third-party pre-compiled root certificates.
