In data structure Hash, hash function is used to convert a string(or any other type) into an integer smaller than hash size and bigger or equal to zero. The objective of designing a hash function is to "hash" the key as unreasonable as possible. A good hash function can avoid collision...

Since MD5 was compromised by this collision attack, using it is no longer recommended.Secure Hash Function (SHA)The four SHA algorithms which make up the SHA family are SHA-0, SHA-1, SHA-2, and SHA-3. Despite coming from the same family, the structure of it differs.The National ...
Since thefinalfunction is non-destructive to the context structure, the function can be used to obtain intermediate "incremental" hashes of the data stream being hashed, and the hashing can then be resumed. The hash value produced via streamed hashing can be used in the discrete-incremental ha...
anincrement(variable)function that checks to see if the passed-in variable equals the array's size and, if so, reset it to 0. Alternatively, the variable can have its value incremented by 1 and thenmod-ed by the size of the array. In such a case, the code forincrement()would look ...
Groups the elements of a sequence according to a specified key selector function and creates a result value from each group and its key. Key values are compared by using a specified comparer, and the elements of each group are projected by using a specified function. ...
