Psiphon is a web proxy designed to help Internet users affected by Internet censorship securely bypass content-filtering systems set up by governments such as China, Iran, North Korea, Cuba, Thailand, Saudi Arabia, United Arab Emirates and others. Psiphon was developed by the Citizen Lab at the University of Toronto, building upon previous generations of web proxy software systems, such as the "SafeWeb" and "Anonymizer" systems.
Psiphon's recommended use is among private, trusted relationships that span censored and uncensored locations (such as those that exist among friends and family members, for example) rather than as an open public proxy. Traffic between clients and servers in the Psiphon system is encrypted using the https protocol.
