<function name="SHA256" parent="util" type="libraryfunc">
	<description>Generates the [SHA-256 hash](https://en.wikipedia.org/wiki/SHA-2) of the specified string. This is unique and will never return the same hash for a different string unlike <page>util.CRC</page> or <page>util.MD5</page> which are both vulnerable to duplicate returns.</description>
