CipherTalkGo is a high-performance, distributed instant messaging application that ensures confidentiality and security of communication through the use of end-to-end encryption and blockchain technology. Developed using the Go programming language, the application is designed to provide a reliable and secure communication environment without storing conversations on the server.

Features

• End-to-End Encryption: All messages are encrypted from sender to recipient, ensuring that only they can read them.
• Distributed Architecture: Users register and interact directly, without the need for data storage on the server.
• Proof of Authorship: Signing each message using the Ed25519 algorithm confirms its authenticity.
• Scalability: Ready for scaling thanks to the ability to add master-slave shards.
• Ease of Use: The CLI interface simplifies the process of connecting and using the application.

Technologies

• Programming Language: Go
• Encryption: ECDH and Ed25519
• Network Protocols: TCP/IP
• Authorization: JWT (JSON Web Tokens)

Development

The application is developed with a focus on the practice and mastery of the following technologies:

• Working with the Go network stack
• Applying principles of security and encryption
• Developing distributed systems
