Certificate Installation Guide

MITM and QUIC modes require a local trust root certificate to decrypt HTTPS traffic and modify the SNI before re-encrypting.

1. Reinstallation Steps (Recommended)

1. Launch SniShaper.
2. In the main interface, find the "Certificate Management" tab or button.
3. Click "Click to Reinstall Certificate".
4. The system will prompt for administrative privileges to install the certificate into the "Trusted Root Certification Authorities" store.

2. Manual Verification

You can verify the installation by checking:

• certmgr.msc -> Trusted Root Certification Authorities -> Certificates. Look for "SniShaper CA".

Warning

Privacy Note: The root certificate is only used locally to decrypt traffic for matching domains. Your data is not uploaded. Clean Up: If you stop using SniShaper, you can manually remove the "SniShaper CA" from your system store.
