[Subresource Integrity](http://www.w3.org/TR/SRI/) tools.

**SemVer note:** As the SRI spec has not yet been finalized, minor releases < 1.0.0 will contain breaking changes.

Install
-------
```shell
npm install sri-toolbox

}, jquerySourceCode);
//=> "sha256-C6CB9UYIS9UJeqinPHWTHVqh/E1uhG5Twh+Y5qFQmYg="
