A number that is generated from a string of text. Hash functions are used to ensure that transmitted messages have not been tampered with. MD5 and SHA-1 are examples of one-way hash functions.
A unique identifying attribute that is attached to text or data in order to distinguish it from all other text, enabling Content Management, assembly and Re-Purposing.
a number calculated in some way from the content of the message (the method is called the hashing algorithm)
a one-way mathematical transformation
a relatively short string of data that represents a large string
a unique and extremely compact numerical representation of a piece of data
The output string from a hash function. See also Message Digest.
A shortened unique identifier for a string of text, generated by applying a formula to the string in such a way that is extremely unlikely that some other string will produce the same hash value.
A number that is generated from a string of text. The hash value (or simply hash), is substantially smaller than the text itself and is generated by a formula in such a way that is extremely unlikely that some other text will produce the same hash value. Hashes are used in security systems to ensure that transmitted messages have not been tampered with and also are used to access data records.
