+generating random data. This class is particularly useful when you need things
+like tokens, nonces, and salts, and is used in several areas of the framework.
+However, we'd prefer to have an entirely static class that provides the same
+functionality, which we can do with PHP builtins.
 
 In the example below, the `Token` class provides two `static` methods:
 
 + `generate`
 + `isHex`
 
-The `generate` method utilizes `random_bytes` for random sequence generation,
-and the `isHex` method verifies the given sequence contains only hexidecimal
-characters.
