Abstract: Systems and methods for licensing a licensor software installation using P2P technology are provided. A computer program product for licensing a licensor software installation for a user includes instructions for receiving a license key for the licensor software and creating a license folder corresponding to the license key. The license folder includes a read-only cryptographic key to use for the license folder to validate the contents of the license folder and a list of users with a license. Additional instructions include adding the user to the list of users with a license and distributing the license folder to a device associated with the user to license the licensor software installation for the user. According to some embodiments, this enables licensing authentication and management for the licensor software in a distributed and serverless way. This may prevent unlicensed use of the licensor software and/or allow licensed use without a licensing server.

Abstract: Systems and methods for file synchronization using P2P technology are provided. In some embodiments, a method of operating a device associated with a user for enabling the sharing of a folder includes creating a Certificate Authority (CA) for the folder. The method also includes granting access to the folder to the user by creating a certificate for the user, signing the certificate for the user with a key of the CA for the folder, creating an Access Control List (ACL) for the user, and signing the ACL for the user with the key of the CA for the folder. The method also includes sharing the folder with a second device. According to some embodiments, this enables the sharing of the folder with no artificial storage limits, increased synchronization speeds, and no need to store the folder on a third-party server.
