ChatCrypt – Secure & Encrypted Messaging

Have you ever wondered how safe your online conversations are from eavesdropping? Admittedly, no one likes their online communication to be monitored by some secret surveillance program like PRISM, unless they are blissfully indifferent to their own privacy. What we’ve been doing the day, what we are planning on doing, where we’re headed next, and even some sensitive financial information is all part of what we regularly communicate with one another on the internet, all without knowing that someone maybe spying on us without our knowledge.

ChatCrypt secure chat is an online chat service that may change a few rules around. The web app allows you to create encrypted chatrooms using a layered security architecture: connections run over WebSocket with TLS, an additional encrypted server layer uses ECDH key exchange and AES-256, and messages during the key exchange phase are RSA-signed. End-to-end member-to-member encryption is handled using ECDH combined with ChaCha20-Poly1305. Importantly, the channel password never leaves your browser, usernames are only transmitted inside the end-to-end encrypted layer, and the channel name is sent to the server only as an SHA-256 hash rather than in plain text. Participants join chatrooms via a shared secret password. Read on for more details.

How ChatCrypt Secure Chat Works

Getting started with ChatCrypt is pretty simple; head over to its website via the link provided at the end of the post. Once there, you are presented with an easily understandable interface carrying a Chat Room login section at the center. The webpage also gives you a detailed explanation about ChatCrypt’s inner workings in order to get you acquainted with it. Furthermore, it also offers webmasters to embed ChatCrypt in their own websites using an HTML embed code.

To create your chat session, look for the ENTER A CHAT ROOM section on home page, specify the name of your chat room, and choose a username and password that will be used to share the same chat room with the other participants. No account, registration, or email address is required at any point — you simply fill in the three fields and connect.

In order to let anyone join in, you will need to provide them with the exact chat room name and the exact same password you chose; all participants must use both the same room name and the same password to communicate with each other. If someone enters the correct room name but a different password, they will not be able to exchange messages with your group — the encryption keys simply will not match. The username — which acts as the identity of each participant — will be different for each chat room member, of course.

Messages are exchanged in real time rather than queued or held; if you send a message while another participant is offline, they will not receive it later. The service is intentionally minimal, built around secure text chat rather than a broad feature set, so do not expect file transfers or voice calling. If you also use other chat platforms, adjusting Discord avatar settings, learning to use formatted Discord text, reviewing options for Telegram account removal, or enabling disappearing WhatsApp messages can similarly help you manage how you communicate and how your identity appears online. After specifying the required details, click the Secure Chat button to enter the main chat area.

ChatCrypt opens up the user-created chat room in a separate window, which also looks quite plain and simple. It contains an input field at the bottom for typing your chat messages. The right side of UI carries the list of members in the chatroom, while the sent messages appear in the main section. Sadly, ChatCrypt lacks any file sharing or voice chat features but considering the nature of the application, there isn’t much else to complain about, as it works exactly as advertised.

What ChatCrypt Secure Chat Stores vs. What It Doesn’t

It is worth being precise about what ChatCrypt actually retains, because “no chat logs” does not mean “no data at all.” On the message side, ChatCrypt requires no accounts and maintains no user database. Real-time chat messages are described by the service as not being queued or stored — once a session ends, the conversation is gone. There are no cloud-based chat logs to subpoena or breach.

That said, the picture is different at the website level. ChatCrypt’s own privacy policy states that the web server keeps log files containing IP addresses, date and time of visits, referring pages, and browser type. Those server logs are retained for 90 days. The site also uses Google Analytics and third-party advertising services, and data associated with those services may be stored for up to 12 months.

The practical takeaway: the content of your encrypted messages is not stored, but your visit to the ChatCrypt website is logged like any other website visit. If that distinction matters for your threat model — for example, if you need to conceal that you used the service at all, not just what you said — you should factor in those web-level logs.

To sum it up, ChatCrypt secure chat is a well-designed tool for keeping the contents of a conversation end-to-end encrypted and out of any stored chat log. For most users who want a quick, account-free, encrypted text session, it delivers on that promise.

However, it is not anonymous in an absolute sense: as noted above, the service’s own privacy policy confirms that server logs including IP addresses are kept for 90 days and that third-party analytics and advertising services are in use on the website. Additionally, because ChatCrypt runs as a browser-delivered web application, users are placing some degree of trust in the code delivered by the service and in the service operator itself — a consideration worth keeping in mind for high-stakes communications.
