My point was that it is irreproducible. folding it over twice with xor's to produce a 32-bit value further helps to randomize the bits. run the result though a DES encryption with the current time as the key. The irreproducibility is the important point. +--- | This is the Midrange System Mailing List! | To submit a new message, send your mail to MIDRANGE-L@midrange.com. | To subscribe to this list send email to MIDRANGE-L-SUB@midrange.com. | To unsubscribe from this list send email to MIDRANGE-L-UNSUB@midrange.com. | Questions should be directed to the list owner/operator: email@example.com +---
