A dictionary attack can also be used in an attempt to find the key necessary to decrypt an encrypted message or document.
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 to index a hash table holding the data or records, or pointers to them. A hash function may be considered to perform three functions: WebMar 26, 2024 · Hash Function: A hash function takes a group of characters (called a key) and maps it to a value of a certain length (called a hash value or hash). The hash value is representative of the original string of characters, but is normally smaller than the original. Hashing is done for indexing and locating items in databases because it is easier ...
