Well RC4 is a stream cipher meaning that it doesn't have an IV. Also the buffer passed to the key argument must contain a key of the required length. If it isn't it will use whatever data is in memory after the supplied pointer. In the case of RC4 the default length is 128 bits so for test purposes use a string with exactly 16 characters in it.
