The danger of cyber-attacks is constant in the current digital environment. The necessity for effective security actions are more crucial than ever before due to the increasingly complex nature of cybersecurity attacks. Using encryption approaches and algorithms is one of the best ways to secure more sensitive data from cyber-attacks. In order to effectively defend against cybersecurity assaults, this research study attempts to give an analysis of the function that encryption methods and approaches serve. We investigate various encryption algorithms and techniques, their advantages and disadvantages, and their applications. In addition, we investigate the difficulties of encryption and the potential solutions to these difficulties.
