(C# UWP/WinRT) ARC4 PRNG (Pseudo Random Number Generator)

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

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

Chilkat.Crypt2 crypt = new Chilkat.Crypt2();

// Set the encryption algorithm to ARC4:	
crypt.CryptAlgorithm = "arc4";

// We want the encrypted output to be a hex-encoded string.
crypt.EncodingMode = "hex";

string key = "000102030405060708090A0B0C0D0E0F";
string data = "12345678";

// Key length is 128 bits in this example.
crypt.KeyLength = 128;
crypt.SetEncodedKey(key,"hex");

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