Метод	Описание
Between ( double startNumber, double stopNumber ) : double	Generates a semi cryptographically strong random integer between specified values. i.e. [startNumber-stopNumber)
ByteBetween ( byte startNumber, byte stopNumber ) : byte	Generates a cryptographically strong 8-bit random integer between specified values. i.e. [startNumber-stopNumber)
GetBytes ( byte buffer ) : void	Fills an array of bytes with a cryptographically strong sequence of random values. The length of the byte array determines how many cryptographically strong random bytes are produced. This method is thread safe.
