About
Telegram Messenger is a cloud-based instant messaging app that syncs across all your devices—phones, tablets, and computers. Send unlimited media and files up to 2 GB each without size restrictions, and create group chats with up to 200,000 members. Messages are encrypted using 256-bit AES, 2048-bit RSA, and Diffie–Hellman key exchange. Secret Chats offer end-to-end encryption with optional auto-deleting messages.
