AzraJabeen Mohamed Ali · Journal of Artificial Intelligence Machine Learning and Data Science · 2023
This paper explores the foundational techniques of hashing and encryption, which are essential for ensuring data protection and integrity in various applications, from secure communications to safeguarding stored data.In today's digital age, securing sensitive information is paramount and cryptography plays a critical role in achieving this goal.Hashing is used to convert input data into fixed-size hashes, providing a way to verify data integrity without exposing the original data, while encryption ensures that information is transformed into unreadable formats, only accessible by authorized parties.Through a detailed examination of popular cryptographic algorithms, such as SHA-256 for hashing and AES for encryption, the paper highlights how these methods are applied in real-world scenarios to protect privacy, prevent unauthorized access and guarantee data authenticity.Additionally, the paper discusses the strengths and weaknesses of each technique, their respective use cases and the evolving challenges in the cryptographic landscape, including computational threats and the potential impact of quantum computing.Ultimately, this study underscores the significance of hashing and encryption as cornerstones of modern cybersecurity practices, offering solutions to safeguard digital assets in an increasingly interconnected world.
