Abstract
The product keys of software applications that can be utilized to identify, and activate to a higher functional state, legitimate copies of such software applications can be asymmetrically encrypted. Such encrypted product keys can be provided to potential purchasers without fear of theft of the original product keys. The encrypted product keys can be provided to an independent, trusted third-party validation authority that can decrypt such encrypted product keys and can, such as in conjunction with the software application manufacturer, verify the validity of the software applications associated with such product keys. For software applications bundled on a computing device, a tool can be executed by either the seller or potential purchaser to collect and display encrypted product keys for verification purposes. For software applications sold in an online environment, an escrow service can be utilized to keep, and provide when requested, product keys of software applications offered for sale.
