Using the well-known cryptographic algorithms SHA-256, SHA-3, MD5, and SHA-512, this study investigates new methods to increase cloud data security utilizing HMAC (Hash-based Message Authentication Code). This effort attempts to secure cloud data storage by preventing unwanted access, alteration, or destruction of private data. The goal is to examine HMAC's compatibility with various hash algorithms and rate how well they protect data from being altered or stolen. This study adds to the existing body of knowledge by combining HMAC with other hash algorithms in a strategic manner, so providing an additional line of protection against cyberattacks. In contrast to more conventional methods, the solution offered by this technology may be easily adapted to work with different cloud environments. This research sets a new standard for the safety of cloud-stored data via rigorous testing and comparative analysis, showing that HMAC-enhanced cryptographic algorithms are more resistant to typical assaults. This study makes a substantial advancement by proposing a workable and scalable approach to resolving current issues in cloud data security.
