In an era defined by using heightened virtual connectivity, the safety and privateness of voice communication are important. This research paper introduces an innovative system designed to establish secure voice communication between two systems. Including a combination of cryptographic algorithms, including RSA, 3DES (Triple Data Encryption Standard), modified RSA, and modified 3DES, the proposed solution gives confidentiality and integrity of voice data during transmission. The need for such a system is underscored by the growing demand for secure communication in sectors where sensitive information is exchanged, such as military and intelligence operations, healthcare, and business. This study explains a client–server architecture where the client system employs RSA and 3DES for encryption, while the server system utilizes corresponding decryption mechanisms. Socket programming serves as the connectivity bridge, with the server’s IP address acting because the transmission key.
