When using Telegrams as a secret chat application, you’ll want to keep a few things in mind. These include time limits, Encryption protocol, and accessibility. Read on to find out what you should know. These features are vital to your privacy and security. You’ll also want to be careful about who can see your private messages, since some people may not have a secure connection.

Time limit for self-destructing messages

When you send a message inside Telegrams secret chat, you can choose to set a time limit to the message that it will be displayed. After this time expires, the message will be deleted. The message’s recipient will need to download it before it disappears.

To enable the timer, first go to the Settings tab. Then, click on ‘Timer’. You can set a timer for one or multiple messages. You can also disable the timer. Messages that have been sent before the time limit is set will not be affected.

Self-destructing messages in Telegrams private chat have a limited duration of 48 hours. This is a way to keep messages out of the hands of people who might want to save them. However, you should use this feature with caution. You should ensure that your recipient trusts you enough not to take screenshots or save messages without your permission.

Another interesting feature that Telegram offers is the ability to set a time limit for photos and videos. This feature allows you to limit how long the messages will stay visible after they have been opened by the recipient. This function is available for both media and Secret Chats. To use the timer, you simply tap the clock icon and then set the time limit for the message to expire.

The Time limit for self-destructing messages is currently off by default but you can change the setting by tapping on the contact profile picture. During this time, the message will be displayed on the recipient’s screen and two green checks appear on the screen. After the time has expired, the message will disappear from their screens.

If you send a message via Telegram secret chat, you must make sure that the recipient does not screenshot it. These messages will not be stored on the Telegram servers. However, they may still remain on the recipient’s device. The best way to make sure your messages are not deleted by the recipient is to set a time limit.

To send a self-destructing message, you must first open the conversation you wish to send it to. Next, select the media you want to send. If you are using a video, choose the “Send with Timer” option. The message will disappear after a certain amount of time or when the video has been watched.

Encryption protocol

Telegram’s secret chat feature uses an encryption protocol known as end-to-end encryption, which means that only the sender and recipient of a message can read it. The secret chats are stored only on the users’ devices, and are not stored in the cloud. This makes Telegrams secret chat a very secure messaging option.

Secret chat files are encrypted with 256-bit random numbers, using the AES-256 encryption. The data is stored in a piece-by-piece fashion. This allows only the recipient to decrypt the message if he or she knows the encryption key. This protects the privacy of both users and the servers.

End-to-end encryption is not the only feature of Telegram that ensures privacy. The private and group cloud chats both support server-to-client encryption. Both types of encryption ensure that every bit of data is treated equally. The apps in Telegram make sure that the message msg_key is equal to the SHA-256 of the auth-key fragment concatenated with the decrypted message. Additionally, the plaintext must always include the message length, the server salt, and the session id.

Telegram’s secret chat features an encryption protocol that was developed specifically for the Telegram network. It was designed to solve problems associated with sending large files over unstable connections, and it does a very good job. This protocol also supports end-to-end encryption, which is essential for restoring chat history in case of a disaster.

End-to-end encryption is also one of the best security features in Telegram, and it prevents hackers from accessing your messages. Although Telegram’s privacy policy confirms that they store user data, it does not explicitly state how the data is used. It uses this information to prevent abuse and violation of the service’s terms. In essence, this means Telegram does not fully belong to the users.


Telegram’s secret chat is a private communication feature, which means that your messages do not pass through Telegram servers. Instead, they are stored locally on your phone until you manually delete them. Occasionally, you might accidentally delete a chat and need to recover it. If this happens, you can back it up using the backup feature or by storing it on an SD card. However, we recommend backing up your chats on a regular basis.


When you use Telegram, you’re exposing yourself to potential security vulnerabilities. The chat application’s code stores metadata for a year, and some of this information can be used to track individual users. For example, the software can track IP addresses and use that information to target an individual’s location. Security experts have been warning users about this for a while, and computer scientists at ETH Zurich and Aarhus University recently reported various security issues.

While it may seem like Telegram is protecting its users’ privacy, it’s still a vulnerable target for hackers and law enforcement. While it offers some impressive security features, it falls short of its competitors in some areas. First, it doesn’t default to end-to-end encryption, which prevents any information from being read or misused by unauthorized parties. Secondly, the encryption keys are split into parts and never stored together with the chat data.

Another drawback of Telegram is that it does not comprehensively encrypt metadata. It also collects IP addresses, which can be used to link users’ contacts lists and phone numbers. This has led to a recent cybersecurity breach in Iran, which resulted in the exposure of personal information of 15 million Iranians. Fortunately, the hackers behind the cyberattack were not government officials, but a hacking group called Rocket Kitten. The group used a fake nude software called DeepNude to create fake identities that could be used to target other users.

Another way to ensure the safety of personal data on Telegram is to set a time limit. If you delete your account, all of your data, including the secret chats, will be removed. Telegram also stores the encryption keys for as long as needed to fulfill obligations. In addition, the chat app does not store credit card information, though it does collect shipping details. However, it does allow users to delete the shipping information.

One more way to protect your personal data on Telegram is to set up two-factor authentication. This is similar to using a password to sign in, but requires a second factor. It is easy to forget this second factor, so make sure you keep it in a password manager.
