- hash function — (programming) A hash coding function which assigns a data item distinguished by some "key" into one of a number of possible "hash buckets" in a hash table.

If, for example, the strings were names beginning with "Mr.", "Miss" or "Mrs." then taking the first letter would be a very poor hash function because all names would hash the same.
