The name stands for "Format-Transforming Encryption."

obfs4 is a randomizing transport: it adds an extra layer of specialized encryption between you and your bridge that makes Tor traffic look like random bytes.If the custom bridge doesn't work, try meek-azure or meek-amazon. If that doesn't work, it may mean that the default bridges are blocked, and you should get a custom bridge from. If it is your first time, try obfs4: it is a randomizing transport that works for most people. There are several pluggable transports, and it can be hard to know which one to use. Pluggable transports disguise the Tor protocol by making it look like something else-for example like HTTP or completely random. Bridges are secret Tor relays-they don't appear in any public list, so the censor doesn't know which addresses to block. Here is how to do it in Tor Browser:Ĭensors block Tor in two ways: they can block connections to the IP addresses of known Tor relays, and they can analyze network traffic to find use of the Tor protocol. But what do you do when Tor itself is blocked? When it happens, you can use bridges and pluggable transports to get around the censors. You can use Tor to view websites that are censored or blocked.
