What is the purpose of hashing?
Hashing is used to index and retrieve items in a database because it is faster to find the item using the shorter hashed key than to find it using the original value. It is also used in many encryption algorithms.
How is a hash generated?
Hashing involves applying a hashing algorithm to a data item, known as the hashing key, to create a hash value. … If we can generate a hash for the record’s key, we can use that hash value as the “address” of the record and move directly to it; this takes the same time regardless of the number of records in the file.
