One of the primary facets for not having end-to-end encryption for groups is the need for accountability and accountability.

When a group chat is end-to-end encrypted, messages are essentially invisble to the platform owner, making it difficult for them to monitor the chat. This can lead to problems like bullying or incivility, which telegram 下载 aims to prevent.

Telegram needs to balance individual users' right to individuality with the need to ensure a respectful community. To achieve this, the platform uses a combination of end-to-end encryption and server-side encryption. This means that messages are encrypted end-to-end between users, which helps ensure that only they can read the content. However, the metadata, such as who sent a message and when, is kept on the servers, allowing Telegram to monitor and track chats if necessary.

Another factor for not having end-to-end encryption for groups is the need to provide features like editing, deletion, and recall of messages. Since end-to-end encryption encrypts messages the moment they leave the sender's device, it can't allow Telegram to keep track of message edits or deletions. By keeping the metadata on the servers, Telegram can provide features like editing and recall, which are highly valued by users.

In addition, the infrastructure required for end-to-end encryption in all types of chats would be completely altered. This may require additional investments, hardware, and capacity, which would be a significant hurdle. Telegram would need to redesign its entire architecture to accommodate the demands of end-to-end encryption in all chats.

While this may seem counterintuitive, Telegram has consistently demonstrated its commitment to user wellbeing and individuality. The platform offers Digtal Security Number, where users can log in to Telegram account using their mobile number. The message encryption between users uses AES 256 symmetric encryption and the elliptic curve Diffie-Hellman (ECDH) key exchange algorithm, which provide high levels of security.

In conclusion, while end-to-end encryption in all types of chats would be attractive, it's not possible from a scientific, feasibility, and pragmatic standpoint. Telegram has to balance individual users' right to privacy with the need to ensure a safe community. The platform continues to innovate and enhance its security features, going beyond simply enabling end-to-end encryption for all chats.
