Users in Iran call it Internet as "Filternet", due to the strict censorship they have on access to Dianetwork. Millions of Iranians are using VPN servers to access the outside world.
In October 2013 Jack Dorsey, its co-founder Twitter asked the Iranian President: “OCan Iranians read your tweets?In response, the Iranian president said he would work to ensure that Iranians have access to information globally and that online censorship is reduced.
Immediately after promising to support Internet freedom, the Iranian government has banned another web application called - Cryptocat , a tool that allows secure and encrypted conversation.
The application is known for the capability of encrypted communication among users, popular with human rights activists and journalists around the world.
According to " Blockediniran.com ", The Cryptocat site and the relatively private chat service was inaccessible to users in Iran.
"Cryptocat is currently the first and only encrypted chat application censored in Iran”Refers to blog post Cryptocat.
“In Cryptocat ο our main goal is to provide easy-to-use, affordable, private conversation around the world. We will do everything we can to allow users in Iran access to Cryptocat along with the rest of the world."
But Iranian users still use Cryptocat. The Cryptocat team provided the chat service through the Tor network, to a hidden deep web site 'catmeow2zuqpkpyw.onion', which can only be accessed using Tor software.
The Cryptocat service may have been used by certain political groups that the Iranian government considered its enemies. Other such encrypted applications are still working and are not yet completely banned in Iran.
Cryptocat is available for Mac and has a plugin for it Chrome and Firefox.
