Conversations
Open Source Conversations app is one of the best encrypted applications for the Android system, which supports the encryption of messages and files through the OMEMO protocol. OMEMO uses secure communication between two parties and supports Forward Secrecy to create a cryptographic key for every message sent. Even if an attacker decrypted a message The attacker can not decrypt other messages. The protocol also supports the transmission of encrypted files and receiving messages if the other party is not connected to the Internet, which is required by the OTR Protocol. Both parties must be connected to the Internet in order to receive and send messages Therefore, the OMEMO protocol gives you better properties than OTR and OPENPGP
The difference between the Conversations application and other communication applications such as Telegram - What's app :
It is an open-source application that security researchers can examine and analyze
The Conversations application supports secure encryption protocols such as OMEMO, OTR and OpenPGP and allows the user to encrypt messages with any of the previous protocols
The Conversations application does not require registration with telephone numbers such as Telegram and What's app but allows the user to register via email on various XMPP servers
The Conversations application supports the selection of XMPP servers, allowing users to freely select servers to send and receive encrypted messages. In this way it is impossible for an attacker to intercept the metadata of your messages before he or she penetrates the server first. However, other communication applications such as Telegram and What's app force you to use the company's servers, Your data is connected to the server, as the message metadata. Facebook and Telegram are able to access the content of your messages stored in servers.
The developer of the Conversations application recently added modifications to the application, including the Blind-Trust feature to accept the encryption keys automatically and to activate the Omemo protocol by default. It also deleted the OTR and OpenPGP from Conversations. Another version of the application, called Conversations Legacy, to suit user requirements So F-droid has two versions of Conversations
The official version Conversations 2.0 which has advanced features but includes the Omemo encryption protocol only (we recommend using it)
The Conversations Legacy version contains different encryption protocols such as OMEMO, OTR and OpenPGP

The server can not represent any of the parties. In the creation of encryption
