![]() ![]() In February 2016, citing dissatisfaction with the project's current state after 19 months of non-maintenance, Kobeissi announced that he would be taking Cryptocat temporarily offline and discontinuing the development of its mobile application, pending a complete rewrite and relaunch of the software. In response, Cryptocat made improvements to user authentication, making it easier for users to authenticate and detect man-in-the-middle attacks. In February 2014, an audit by iSec Partners criticized Cryptocat's authentication model as insufficient. In response, Cryptocat issued a security advisory, requested that all users ensure that they had upgraded, and informed users that past group conversations may have been compromised. Private messages were not affected, and the bug had been resolved a month before. In June 2013, security researcher Steve Thomas pointed out a security bug that could be used to decrypt any group chat message that had taken place using Cryptocat between September 2012 and 19 April 2013. He tweeted about the incident afterwards, resulting in media coverage and a spike in the popularity of the software. border by the DHS and questioned about Cryptocat's censorship resistance. In June 2012, Kobeissi said he was detained at the U.S. Ĭryptocat was created by Nadim Kobeissi and further developed along with a community of open source contributors and is published under the terms of the GPLv3 license, although it has since been discontinued.Ĭryptocat was first launched on as a web application. Users are given the option of independently verifying their buddies' device lists and are notified when a buddy's device list is modified and all updates are verified through the built-in update downloader. It uses end-to-end encryption to secure all communications to other Cryptocat users. Of making encrypted instant messaging accessible and portable.Cryptocat is a discontinued open-source desktop application intended to allow encrypted online chatting available for Windows, OS X, and Linux. Highly accessible mediums, and to address the technical and social challenges Goal is to investigate the feasibility of implementing cryptographic systems in Privacy is not achieved without addressing the problem of accessibility. If a cryptographic system is technically highly qualified, securing user That accessibility and ease of use must be treated as security properties. We have found that encrypted communications, while in manyĬases technically well-implemented, suffer from a lack of usage due to theirīeing unappealing and inaccessible to the "average end-user". Order to allow encrypted instant messaging an opportunity to better permeate onĪ social level. We aim to investigate how toīest leverage the accessibility and portability offered by web technologies in Makes use of web technologies in order to provide easy to use, accessible,Įncrypted instant messaging to the general public.
