Abstract

This survey presents a comprehensive examination of diverse encryption and decryption techniques, encompassing historical methods like DES to modern approaches such as elliptic curve cryptography and genetic algorithms applied to 3-DES encryption. The paper explores the operational principles, security features, and practical considerations of each cryptographic method, shedding light on strengths, potential vulnerabilities, and real-world applicability. Key aspects such as encryption and decryption efficiency, security mechanisms, and the interplay between symmetric and asymmetric cryptography are addressed. The survey aims to guide researchers, practitioners, and policymakers in making informed decisions for robust and secure data communication and storage. Additionally, the paper identifies potential areas for future research, emphasizing advanced encryption techniques, secure key management, and the integration of cryptographic methods to address emerging challenges in data security.
