Does Telegram have proper E2E encryption for chats by default?

• kitkat_new 5y ago
  no and it is not even available for multi-device and group chat

    It makes sense because you shouldn't want messaging app's backend to transfer your device specific private encryption key across all your registered devices.

      why shouldn't I?

  Nope, but I come from an IRC background so having unencrypted chats is perfectly normal. YMMV. I've been chatting in unencrypted channels since the mid 90's so I don't exactly see E2EE as a hard requirement. I'll switch my family chat to Signal or whatever as soon as I can add my home automation bot in there without some weird hacks or custom clients. The current implementation is a glorified Curl call for Discord and maybe 20 lines of Python for Telegram.

  Not on by default for 1 to 1 chat but it (Secret Chat) is optional, drawback is that the end-to-end encrypted conversation stays only on the devices initially it was initiated, because the encryption keys stay only on those 2 devices. For Telegram Group Chat - it is not end-to-end encrypted, Telegram uses distributed infrastructure approach to protected data not covered by End-to-End encryption. I wouldn't consider WhatsApp's Group Chat end-to-end encrypted.
