Conversations is a Jabber/XMPP client for Android 4.0+ smartphones that has been optimized to provide a unique mobile experience.[3] Easy to use, reliable, battery friendly. With built-in support for images, group chats and e2e encryption.[1]

Development is focused on secure communication and implementation of XMPP extensions that are important for mobile usage. Specialist publications praised the decentralized and open transmission network and simple, intuitive usage with a workflow that is familiar from other applications. It is regarded as a serious attempt to improve the usability of XMPP-based messaging to a competitive level.[4]

History[edit | edit source]

On January 24, 2014, first code was submitted to the public repository.[5] The first official version 0.1 was published on March 24, 2014[6] when encrypted messengers for mobile devices gained a lot of popularity in the wake of the Snowden disclosures (June 2013) and Facebook's acquisition of WhatsApp (February 2014).[7] It soon garnered some positive reviews.[4][8] In spring 2014 it was included into Google Play and starting with version 0.1.3 from April 6, 2014 into the alternative Android software repository F-Droid.[9] Since version 0.2 from May 12 picture messages (file transfers, as plain-text data or OpenPGP-encrypted) are supported, as of version 0.4 (June 30) also OTR-encrypted.[10][11] Version 1.0 followed on February 1, 2015.[12] Andreas Straub participated in the Google Summer of Code 2015 on behalf of Conversations.[13][14] This produced drafts for a new end-to-end encryption standard (OMEMO) that were submitted to the XMPP Standards Foundation (XSF) for standardisation.[15][16] In October 2015 the ChatSecure project announced that it is going to base the Android version of its messenger on the Conversations core and to be working on an iOS implementation of OMEMO.[17]

OMEMO[edit | edit source]

OEMEO Multi-End Message and Object encryption is an XMPP Extension Protocol (XEP) for secure multi-client end-to-end encryption. It is an open standard based on a Double Ratchet and PEP which can be freely used and implemented by anyone. The protocol has been audited by a third party.[19]
