ARC4 PRNG (Pseudo Random Number Generator)

Uses the ARC4 stream encryption algorithm as a pseudo random number generator. Xbase++

//  See Global Unlock Sample for sample code.

//  Key length is 128 bits in this example.

//  Generate 16 "random" 8-byte blocks, encoded as hex strings.
//  This example will generate the identical output each time
