Because of the fast use of cloud computing, effective security measures have become necessary in order to safeguard sensitive data from being accessed by unauthorised parties and from being compromised. The encryption of data is an essential component of cloud security, since it guarantees the confidentiality and integrity of data while it is being stored and sent. Within the scope of this work, a number of distinct encryption methods, including as symmetric key encryption, asymmetric key encryption, and homomorphic encryption, are investigated. The advantages, limits, and appropriateness of these encryption approaches for various cloud settings are discussed. A strong emphasis is placed on the role that encryption plays in maintaining regulatory compliance, minimising risks associated with eavesdropping, and safeguarding communications from beginning to finish. In addition, we investigate hybrid encryption strategies, which combine the advantages of symmetric and asymmetric systems in order to strike a balance between efficiency and security. Another topic that is covered is the difficulties associated with key management, performance overhead, and interaction with the cloud infrastructure that is already in place. The use of encryption frameworks to protect cloud storage and communication in areas such as healthcare, banking, and e-commerce is demonstrated through case studies that are based on real-world scenarios. In the future, there is the possibility of developing encryption that is resistant to quantum computing in order to combat the dangers that are posed by quantum computing. The purpose of this study is to provide organisations with a guidance that can assist them in improving their cloud security postures by utilising modern encryption technology.
