+
+Called on an *individual* `IntegrityMetadata` object, will convert its `digest`
+to a hex representation of the base64 data.
+
+##### Example
+
+```javascript
+ssri.parse('sha1-deadbeef', {single: true}).hexDigest() // '75e69d6de79f'
+```
+
 #### <a name="from-data"></a> `> ssri.fromData(data, [opts]) -> Integrity`
 
 Creates an `Integrity` object from either string or `Buffer` data, calculating
