A string of text is converted to a numeric value that uniquely identifies the original text. With only the numeric value it is impossible to reproduce the original text value. Which term correctly identifies this numeric value?

#### Answer Description

A hash value, hashed value or just a hash is the result of a one-way cryptographic function. Hashes are used to verify the integrity of data (e.g. a file download) as well as to store sensitive data such like passwords.

#### Wikipedia

A cryptographic hash function is a special class of hash function that has certain properties which make it suitable for use in cryptography. It is a mathematical algorithm that maps data of arbitrary size to a bit string of a fixed size (a hash) and is designed to be a one-way function, that is, a function which is infeasible to invert. The only way to recreate the input data from an ideal cryptographic hash function's …
