UseCrypt Messenger – a secure messenger available to a smartphone, which makes it possible to hold encrypted messages and calls in HD standard. Whole communication via Usecrypt Messenger is secured with end‑to‑end encryption with all cryptographic operations made on user’s device.

SECURING DATA FROM THE LEVEL OF DEVICE/PHONE (AT-REST) – it encrypts the APPLICATION (conversations, chats and call history in the application on the device/phone) making it impossible to extract/take-out anything from the app/phone). Phone operating system copies all the conversations, chats and history of talks and allows to extract it from the phone. The application protects your data in the App, when: loosing phone, stealing phone, giving to 3rd party to service, giving to your employer/company’s phone with private messengers), giving away to security institutions, remote attacks by hackers and business competitors, when leaving the phone unattended.

INDEPENDENT PASSWORD – The App has Enter Code that is independent to the operating system, making it impossible to open the application by unauthorized person (after breaking the screen lock of the phone).

THE ONLY APP THAT CAN DETECT IF YOUR PHONE HASN’T BEEN HACKED – Usecrypt is the only App that checks/inspects if your microphone and speaker is hacked; each time your open Usecrypt Messenger the App checks if UseCrypt Messenger is one and only App with access to microphone and speaker at that very point of time, it also checks if you do not have malicious apps on your phone.

PANIC CODE – The App has Panic Code; when forced to open the App the Panic Code erases the entire history and disconnect the Service leaving the App empty.

UNTRACEABLE IP – It is NOT using webRTC protocol that most of the Apps are and that allows easily to see to whom you called and where the person was; it gives full IP anonimity.

SERVERS DON’T STORE ANY DATA – By design the app’s server application never stores any history of calls, conversations and text messages – technically never touch your data so it cannot give it away.

PRIVACY FOR EMPLOYEE – That encrypts the conversations, chats and call history of the application on the device/phone (making it impossible to extract anything from the app).

CoyIM – a standalone chat client that focuses on safety and security. It is a self-contained program that runs on Windows, Linux and macOS. CoyIM only supports one chat protocol – XMPP (Jabber). It is built upon xmpp-client and coyim otr3, and adds a graphical user interface and implies safe and secure options by default.

The developers ambition is that it should be possible for even the most high-risk people on the planet to safely use CoyIM, without having to make any configuration changes. To do this, CoyIM has OTR enabled and uses Tor by default. Besides that, it will only use the Tor Onion Service for a known server and also uses TLS and TLS certificates to verify the connection – no configuration required. The implementation is written in the Go language, to avoid many common types of vulnerabilities that come from using unsafe languages.

Main features:
– Support of the latest version of OTR.
– Detection of Tor (if installed) and connection through it.
– Use of Tor Onion Service if it is known by the server in question.
– Use of separate Tor circuits for each account in order to make it harder to tie accounts together.
– Insertion of random delays before connecting to each account in order to make fingerprinting of connections between accounts harder.
– SRV lookup for the server over Tor if available.
– Import of account settings, OTR settings, fingerprints, and private keys from other clients like Pidgin, Adium, Gajim or xmpp-client.
– Saving of all your configuration, including OTR fingerprints and keys, in an encrypted configuration file.

Pidgin (formerly named Gaim) – a chat program which lets you log in to accounts on multiple chat networks simultaneously. This means that you can be chatting with friends on MSN, talking to a friend on Google Talk, and sitting in a Yahoo chat room all at the same time. The program was originally written by Mark Spencer, an Auburn University sophomore, as an emulation of AOL’s IM program AOL Instant Messenger on Linux using the GTK+ toolkit.

Pidgin is compatible with the following chat networks out of the box: AIM, ICQ, Google Talk, Jabber/XMPP, Bonjour, Gadu-Gadu, IRC, Novell GroupWise Messenger, Lotus Sametime, SILC, SIMPLE and Zephyr. It can support many more with plugins.

Pidgin supports many features of these chat networks, such as file transfers, away messages, buddy icons, custom smiles, and typing notifications. Numerous plugins also extend Pidgin’s functionality above and beyond the standard features. Pidgin is widely used for its Off-the-Record Messaging (OTR) plugin, which offers end-to-end encryption.

Pidgin integrates with the system tray on Windows, GNOME2, KDE 3 and KDE 4.
