E-mail-based messenger with end-to-end encryption
|
|
---
|
|
|
|
Messengers like Telegram, Signal, Whatsapp cannot be private due to the peculiarity of their architecture - centralization. And peer-to-peer (p2p) services like [Tox](https://tox.chat/) consume too many resources and are inconvenient to use on a mobile device. The best solution is to use **your own** mail server for [Delta Chat](https://delta.chat). The application is available for all popular desktop and mobile systems.
|
|
|
|
If your conversation partner doesn't use Delta Chat, it will be just an ordinary email correspondence for him.

## Typical data leaks when using alien servers
|
|
1. IP once per minute. Helps determine your location: at home, away from home, at work.
|
|
2. The content of your messages.
|
|
3. Meta-information: with whom and when you communicated, even if you use encryption.
|
|
|
|
## Features of Delta.Chat
|
|
|
|
- Regular email client with all the features of IM.
|
|
- Reliable end-to-end encryption (e2e), provided a personal [email server]({{< ref "email.md" >}}) is used by both interlocutors or a personal key exchange, such as via QR code.
|
|
- Can use any email server, but then you lose control over the meta-information and [risk](https://s.zholnay.name/@kirill/106351532683026396) key-swapping [man-in-the-middle attack](https://en.wikipedia.org/wiki/Man-in-the-middle_attack).
|
|
- Slightly slower than usual messengers
|
|
- First message is not encrypted because public encryption keys are sent with it.
|
|
- There are problems with sending files > 5-7MB.
|
|
- There are no convenient channels (chats for mass discussions and sending out information). We recommend using [a decentralized social network]({{< ref "pleroma.md">}}). |
