 Basically, the program obtains a small amount of keying material from the packet then attempts to send ARP and/or LLC packets with known content to the access point (AP).  If the packet is successfully echoed back by the AP then a larger amount of keying information can be obtained from the returned packet.  This cycle is repeated a several times until 1500 bytes of PRGA are obtained or sometimes less then 1500 bytes. Basically, the program obtains a small amount of keying material from the packet then attempts to send ARP and/or LLC packets with known content to the access point (AP).  If the packet is successfully echoed back by the AP then a larger amount of keying information can be obtained from the returned packet.  This cycle is repeated a several times until 1500 bytes of PRGA are obtained or sometimes less then 1500 bytes.
