About:
obfs4proxy is a pluggable transport for Tor that disguises Tor traffic to circumvent network censorship and filtering. It implements the obfs4 protocol, which uses elliptic curve cryptography and random padding to make traffic look like random bytes. This helps users access the Tor network in restrictive environments where Tor is blocked.
Key Features:
  • Implements obfs4 protocol with elliptic curve cryptography
  • Resistant to active probing and deep packet inspection
  • Integrates seamlessly with Tor as a pluggable transport
  • Cross-platform support including Linux, macOS, and Windows
Use Cases:
  • Circumventing internet censorship in restrictive regions
  • Protecting Tor access from network-level detection and blocking
  • Securing communications in high-risk environments
Alternatives:
  • meek – Uses domain fronting via CDN providers, higher bandwidth overhead but harder to block
  • Shadowsocks – General-purpose encrypted proxy, not Tor-specific but similar anti-censorship goals
