* Random kind selector

* The kind of random denotes the statistical quality of the random data
* returned. Basic random simply appears uniformly distributed, Cryptographic
* random is statistically random and suitable for use by cryptographic
* functions. True random is generated from a hardware entropy source rather
* than an algorithm and is thus completely unpredictable. These form a
* hierarchy where higher quality data is presumably more costly to generate
* than lower quality data.
