FIXME: Currently this function is just a stub, it is missing functionality in
the following (major) ways:
(1) It makes no use of the passed in HCRYPTPROV handle. (ie. it doesn't
use a cryptographic service provider (CSP)
(2) It doesn't use the values in the passed in pbBuffer to further randomize
its internal seed.
(3) MSDN mentions that this function produces "cryptographically random"
data, which is "... far more random than the data generated by the typical
random number generator such as the one shipped with your C compiler".
We are currently using the C runtime rand() function. ^_^
See MSDN documentation for CryptGenRandom for more information.
