Hashing is a process that takes in data and generates a fixed-length output, called a hash value. This allows for efficient data retrieval and comparison, as the original data can be identified by its corresponding hash value. Option A is incorrect because hashing is not encryption and does not use keys. Option C is incorrect because while it can be used for authentication, it is not the primary purpose of hashing. Option D is incorrect because hashing uses the same key for both encryption and decryption. Therefore, option B is correct because hashing allows for data to be encrypted in a way that cannot be decrypted, providing an added layer of security for sensitive information.
