This API supports the product infrastructure and is not intended to be used directly from your code. Implements the SGen task. Use the SGen element in your project file to create and execute this task. For usage and parameter information, see SGen Task.
What is a cryptographic hash? A hash (also called a digest, and informally a checksum) is a kind of signature for a stream of data that represents the contents. The closest real-life analog we can think is a tamper-evident seal on a software package: if you open the box (change the file), it's detected.
Hashing means using some function or algorithm to map object data to some representative integer value. This so-called hash code (or simply hash) can then be used as a way to narrow down our search when looking for the item in the map.n this and the following pages, we explore hashing, a technique used (among other applications) to implement Java's common map and set classes.
