There's nothing secret about the algorithm that the key fob uses to produce numbers, so reverse engineering it wouldn't get you anything that isn't published publicly. What is secret is the initialization vector with which a given device began its life. That's no longer useful from the device you've got (because it's no longer generating values, which means no values generated based on its IV will be accepted by the authentication server), and, even if it were, the key fob is tamper- proof, designed to destroy exactly this piece of secret information if anybody tries to open it. > (I wonder if it would sell on ebay.) Probably. Belly-button lint will sell on eBay. -- gabriel rosenkoetter gr@eclipsed.net Attachment:
