Basically, you must build a desktop/android application that utilizes cryptographic techniques/protocols to secure communication (or data at rest). Try to achieve confidentiality, integrity, availability, authentication, non-repudiation (preferably all of them, otherwise few of them based on the requirement).You must demonstrate the use of these cryptographic techniques by showing some outputs/visualization results or captured traffic such as through Wireshark.1. Secure Chat ApplicationDescription: Build an encrypted chat application for desktop or Android that ensures confidentiality, integrity, authentication, and non-repudiation.Features:-- End-to-end encryption using AES-256 or Signal Protocol.--Digital signatures for non-repudiation.--Message integrity verification using HMAC.Secure login using two-factor authentication (2FA).--Server-side availability mechanisms (e.g., load balancing, backup storage). Technologies: Python (PyQt + PyCryptodome), Java (Android), Firebase for…
