An unidentifiable mechanism that helps you bypass network restrictions.
Trojan features multiple protocols over TLS to avoid both active/passive detections and ISP QoS limitations. It doesn't rely on strong encryption or obfuscation; instead it imitates the most common protocol, HTTPS, so firewalls won't see anything other than normal HTTPS traffic.
To install trojan, paste this in macOS terminal after installing MacPorts
sudo port install trojan
