Hash calculation algorithm

A hash function takes a key as an input, which is associated with a datum or record and used to identify it to the data storage and retrieval application. The keys may be fixed length, like an integer, or variable length, like a name. In some cases, the key is the datum itself. The output is a hash code used … See more A hash function is any function that can be used to map data of arbitrary size to fixed-size values, though there are some hash functions that support variable length output. The values returned by a hash function are called … See more Hash functions are used in conjunction with hash tables to store and retrieve data items or data records. The hash function translates the key … See more There are several common algorithms for hashing integers. The method giving the best distribution is data-dependent. One of the simplest and most common methods in practice is the … See more Worst case result for a hash function can be assessed two ways: theoretical and practical. Theoretical worst case is the probability that all keys map to a single slot. Practical worst case is expected longest probe sequence (hash function + collision resolution … See more Uniformity A good hash function should map the expected inputs as evenly as possible over its output … See more When the data values are long (or variable-length) character strings—such as personal names, web page addresses, or mail messages—their distribution is usually very … See more The term hash offers a natural analogy with its non-technical meaning (to chop up or make a mess out of something), given how hash functions scramble their input data to derive their … See more WebHash is an algorithm that converts input data of any length into fixed length output, and the output result is the hash value.
