obfs4 wraps Tor cells in a randomized cover stream that is statistically indistinguishable from random binary data. State censors blocking by deep packet inspection cannot fingerprint obfs4 the way they fingerprint vanilla TLS-on-9001. Romania bridge VPS ship with obfs4proxy preinstalled.

Listening on 443 is intentional: censors are less likely to block 443 wholesale. The obfs4 stream is application-layer-indistinguishable from generic encrypted traffic on that port.
