JabNet Messenger

This is a secure messenger written in C# that is currently in development

Plans for supported platforms: Windows, Android

Not defined plans for other platforms: iOS

Currently maintained by:

• FrogCpp
• Gyroscopic-why

For the data encryption we use a custom algorithm: RE

You can check more about the algorithm here

(The active encryption algorithm version will be: RE5 + Hashing)

For client-server communication we use custom USC - universal server commands

They include:

• Secure connection with the server________________________________________(usc: CONSC)
• Standart authorisation request ___________________________________________(usc: STDAU)
• Special authorisation request (AutoAuth request)________________________(usc: SPDAU)
• Login change request_____________________________________________________(usc: CHLOG)
• Password change request_________________________________________________(usc: CHPAS)
• Account deletion request_________________________________________________(usc: DELAC)
• Get contacts (for the singed in account)__________________________________(usc: GETCT)
• Get groups (that the signed in account is in) _____________________________(usc: GETGR)
• Get history for a selected chat w amount of wanted messages __________(usc: GETHS)
• Send message ____________________________________________________________(usc: SENDM)
• Send picture ______________________________________________________________(usc: SENDP)
• Send file __________________________________________________________________(usc: SENDF)
• Get usID (Get a fast sequre unique session id for the user) ______________(usc: GTSID)
• Change usID (to log out other devices from your account) ______________(usc: CHSID)
• Reconfigure Uencryption key (Change encryption key) __________________(usc: CHUEK)
• Secure reconfigure Uencryption key (Safe change encr key) _____________(usc: SCUEK)

For server data storing we use sql databases

Current structure for the databases can be found inside this project (v2.1)

Goals for this project:

• Add server logic
• Add server-client communication through usc
• Finish the data storing in a database
• Establish secure communication between the server and the client
• Finish client logic
• Add client UI
• Add multi language for the UI
• Buy a server
• Buy a static ip for a web version (?)
• Release the messenger to the public (?)
