BatChat-Messenger for iPhone

Product snapshot

BatChat-Messenger is a secure, end-to-end encrypted messaging application built to protect user privacy and communications. Backed by roughly a decade of development and used by millions, it positions itself as a major player in the secure-communications space and focuses on keeping personal data and conversations private.

Security and transport protocols

The application uses RSA and SRP schemes alongside asymmetric cryptography to guard user keys and sessions. For message transfer it employs an additional proprietary "double-spiny" algorithm to reinforce transport security, and overall messaging is protected with end-to-end encryption so only participants can read content.

Key capabilities

• Encrypted group conversations that can scale to thousands of participants.
• Read receipts, password-based unlocking, and threaded group discussions for better control and collaboration.
• Support for multiple message types — text, images, voice, and video calls — delivered with minimal server-side handling.
• Full end-to-end encryption across chats and calls to keep messages confidential.
