Generate output bytes using a pseudorandom function (PRF).
public static byte[] Bytes( int numBytes, byte[] message, byte[] key, Prf.Alg prfAlg, string customStr )
Public Shared Function Bytes ( _ numBytes As Integer, _ message As Byte(), _ key As Byte(), _ prfAlg As Prf.Alg, _ customStr As String _ ) As Byte()
VB6/C equivalent: PRF_Bytes
