It also allows you to speak with servers that don’t natively support SSL/TLS without downgrading your encryption.įor purely evading censorship, Shadowsocks was created in 2012 to evade Chinese internet censorship and firewall. Similar to Obfsproxy, it can mask SSL/TLS traffic to appear like HTML. Stunnel, for one, is an open-source obfuscation technology that’s been around since the 1990s. Its developers managed to add a wrapper around Tor’s traffic without leaving any evidence.

It can be tricky to add an encryption layer without a trace. But Can’t Obfsproxy be Detected and Blocked? All Obfsproxy does is make your ultra-secure and anonymous browsing look like everyday web surfing. Depending on the policy, anything from Tor to VPNs and even self-hosted proxies could be blocked. You can’t entirely avoid DPIs, but you can hide your traffic in plain sight. In some instances, these tools can take direct actions and prevent a cyberattack or stop you from connecting to a suspicious server. This allows them to determine the type of encryption, whether it’s SSL, HTTPS, Bittorrent, or VPN.ĭPIs and network monitoring tools aren’t strictly for surveillance. While they can’t decrypt network traffic, they are able to look at the hints data packets publicly give. You can find such algorithms in all kinds of network monitoring tools such as Wireshark and Glasswire. Deep Packet Inspection (DPI) is a type of data processing that inspects data moving through a network.
