An algorithm that maps or translates one set of bits into another (generally smaller) so that a message yields the same result every time the algorithm is executed using the same message as input. Sco [..]

An algorithm that computes a value based on a data object thereby mapping the data object to a smaller data object.

1.  A mathematical function that maps values from a large (or very large) domain into a smaller range, and that reduces a potentially long message into a "message digest" or "hash value" or that is sufficiently compact to be input into a digital signature algorithm. Note: A "good" hash function is one that results from [..]

A hash function is a function that maps a bit string of arbitrary length to a bit string of fixed length. The values returned by a hash function are called hash values, hash codes, hash sums, checksum [..]

A function that maps a string of arbitrary length to a fixed size value in a deterministic manner. Such a function may or may not have cryptographic applications.

A cryptographic hash, also called a message digest, is a publicly-known function that takes as its input a message of (almost) any length and compresses it into a random-like short message called a di [..]

A Hash Function is a transformation that takes an input and returns a fixed-size string, which is called the hash value (sometimes termed a message digest, a digital fingerprint, a digest or a checksu [..]

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 characte [..]

A function which takes an object as its input, and produces an integer value as its output. Good hash functions produce outputs that are as random as possible, i.e., they have the property that differ [..]

A function used to produce a hash code from the arbitrary contents of an object. Classes can override the hashValue method, inherited from the Object class, to define their own hash function.
