CipherMQ; a new generation Message Broker written by Rust

In an era where data breaches and system vulnerabilities make headlines daily, building secure messaging infrastructure isn’t optional — it’s essential. Modern applications handle sensitive financial data, personal information, and critical business communications that attackers constantly target.

Rust empowers CipherMQ with an uncompromising combination of blazing performance and rock-solid reliability. The language’s zero-cost abstractions and compile-time memory management deliver consistent low-latency message processing without the unpredictable pauses of garbage collection, while its revolutionary ownership system prevents entire classes of bugs like buffer overflows and data races that could corrupt messages or crash the system. This means CipherMQ can handle high-throughput scenarios with predictable performance characteristics while maintaining the memory safety guarantees critical for a reliable message queue — essentially giving you C-level speed with the safety of higher-level languages, all validated at compile time rather than discovered in production.

Okay, you get it. We are developing a new generation message broker, and in the upcoming parts of this article, I will explain the whole project. Just follow along.

If you’re a Data Engineer, Software Engineer or DevOps engineer frustrated with the complexity of securing data transmission, CipherMQ is the solution you’ve been looking for. Just keep reading this blog.

What is CipherMQ?

CipherMQ is a secure message broker system designed to transmit encrypted messages between senders and receivers using a push-based architecture. It leverages hybrid encryption (RSA + AES-GCM) to ensure message confidentiality and authenticity. The system guarantees zero message loss and exactly-once delivery through robust acknowledgment mechanisms. Messages are temporarily held in memory (without persistent storage except for logs and receiver output) and routed through exchanges and queues to connected consumers.

Why CipherMQ is so secure?

Now that you have an overview of CipherMQ, let’s dive deeper into how it works behind the scenes.

Suppose someone (the receiver) wants to get some records or messages. The receiver must first generate a key pair and share their public key with the sender, while keeping the private key secure on their own system for decryption. A server sits between these two parties to facilitate message routing.

The sender encrypts messages using both the receiver’s public key and AES-GCM encryption, creating two layers of security. After encryption, the messages are sent to the server, which routes them to the receiver before deleting the records from its storage.

If anyone intercepts these records over the network, they cannot decrypt or understand the content without access to the private key, which remains safely stored on the receiver’s system. In our upcoming release, we’re adding another layer of security: TLS to establish secure sessions between the sender and server, as well as between the server and receiver.
