Browser-Based End-to-End Encrypted Private Messaging

Traditional messaging platforms like WhatsApp, Telegram, and Signal require mandatory phone number registration, cloud account synchronizations, and app installations. For temporary conversations, confidential business exchanges, or ad-hoc collaboration, sharing your personal mobile number creates unnecessary privacy risks.

ChatCrypt (Crypt Chat) was created to provide a completely ephemeral, zero-knowledge messaging environment directly in your web browser. Room encryption keys are generated locally using the standard Web Crypto API (AES-256-GCM) and passed solely through URL hash fragments, meaning our servers never see or store your plaintext conversations.

Frequently Asked Questions

How does ChatCrypt encrypt messages without an account?

When you create a room, your browser generates a random 256-bit symmetric key using the Web Crypto API. The key is embedded in the URL after the # hash symbol. Because browsers never send URL hashes to web servers, the encryption key remains strictly on client devices.

Can ToolsWebPro administrators read my private chat messages?

No. The server only relays encrypted ciphertext payloads. Without the client-side decryption key residing exclusively in your browser memory, the messages appear as random binary data that cannot be decrypted by anyone in transit.

What happens when a chat room is closed or expires?

When the host ends the room or when a room reaches its idle timeout, all associated session records are deleted immediately from memory. There are no persistent database archives or backup logs.

Does ChatCrypt work across different devices and mobile browsers?

Yes. ChatCrypt works in all modern desktop and mobile browsers supporting the Web Crypto API, including Safari (iOS/macOS), Chrome (Android/Windows/Mac), Firefox, and Microsoft Edge.

ChatCrypt (Crypt Chat) encrypts messages in your browser before they are sent. These guides explain how it works, how to share rooms safely, and how it compares with regular messaging apps.
