Dib2Qm Encrypted Messaging app for Android description
Dib2Qm (aka Dibdib Messenger)
Messenger for secured chats and groups (end-to-end encrypted).
Dib2Qm is a messenger that works via e-mail servers, end-to-end encrypted.
Currently only as transitional version! It is not supported by newer versions of Android.
Text messages are not only end-to-end encrypted, they also get stored on your device in an encrypted way. Images, attachments etc. can be sent -- encrypted, of course, but since they depend on third-party programs, they are stored unencrypted. Dib2Qm makes use of your devices Download folder (also for backups and archives).
You need an e-mail account (on a server with standard IMAP and SMTP services), for which a small app like this one is allowed to access the services.
Just try it out! -- on a non-critical device (And if your e-mail provider blocks it, use a different provider. Dib2Qm does not depend on a centralized server.)
- You can only chat with people who also use Dib2Qm.
- After the setup, please first start the messaging service (via menu).
- If you get a connection, the status should turn green (... ON).
- Add a contact, via menu: you have to enter the other ones e-mail address.
- If you then touch the new contact, you will be asked to send the invitation (i.e. the key info for exchanging secured messages).
- Once the key exchange is completely done (black/red, orange, green), the chat works similar to other apps.
If one of your chats gets stuck (due to a key exchange problem), just send another invitation from within the chat.
It is possible to use the address of your devices Google account, but they insist on you explicitly allowing messenger apps: you would log in with your browser (!), go to Settings, Forwarding...IMAP, Enable IMAP, Save, then to Accounts, Other ... settings, ...Security, 2-Step..., Off, and Connected apps, Allow less secure, On.
Strange? It is easier to use an extra e-mail account for Dib2Qm, but depending on your provider you might still have to allow IMAP services. Both, using the devices account address or using a dedicated e-mail address for Dib2Qm, have their advantages and disadvantages ...
If you want to do a complete re-start, go to the devices settings, clear the app data, then open a file manager, clear the Download/dibdib data, and then you can start the app a-fresh.
