Around the world repressive governments are trying to stop Internet users from either posting anonymously or using encryption to communicate securely. Russia requires bloggers with more than 3,000 visitors to register with the state and identify themselves; pseudonyms are outlawed in Vietnam; Ecuador requires commenters on websites to use their real name; Pakistan’s government must grant approval for the use of encryption; and Ethiopia convicted members of the dissident blogging collective Zone 9 on terrorism charges based in part on participation in an online encryption workshop.
