WebHash Table. Hash table is one of the most important data structures that uses a special function known as a hash function that maps a given value with a key to access the elements faster. A Hash table is a data structure that stores some information, and the information has basically two main components, i.e., key and value. WebExamples of cryptographic hash functions are MD5 and SHA-1. Some attacks are known on MD5, but it is faster than SHA-1 and still fine for use in generating hash table indices. Precomputing hash codes. High-quality hash functions can be expensive. If the same values are being hashed repeatedly, one trick is to precompute their hash codes and ...
