Instantiating an attestation facilitation component that allows a remote application to attest to a secure state of a secure memory application executing upon a secure platform of a computer system regardless of a type of either the secure platform or a health attestation service. Instantiation comprises identifying a property that includes at least one of the secure platform type and the health attestation service type. The instantiation is customized with the identified property. The attestation facilitation component verifies that a report generated by the secure platform represents that the secure memory application is operating in a secure state, and accesses a token generated by the health attestation service that represents that the secure platform is operating in a secure state. The attestation facilitation component generates a quote that allows the remote application to verify that the secure platform and the secure memory application are both operating in secure states.

One or more techniques and/or systems are provided for generating a bundle package, digitally signing the bundle package, selectively disturbing the bundle package, and/or indexing one or more resource packages retrieved from the bundle package. That is, a bundle package (e.g., an application or game bundle package) comprises one or more app packages comprising application code configured to execute on various computing environments (e.g., operating systems, processors, etc.). The bundle package may comprise one or more resource packages comprising supplemental data used to provide optional user experience functionality for the application (e.g., French language support, high resolution textures, a gaming pad support, etc.). In this way, a client device may selectively download portions of the bundle package that may be relevant, which may mitigate download bandwidth, storage space, or resources otherwise used to obtain unnecessary portions of the bundle package (e.g., a tablet device may merely download low resolution textures).

Systems and methods are disclosed for recovering data. The disclosed systems and methods may include locating a central directory in a file archive. Furthermore, the disclosed systems and methods may include determining that a local header located in the file archive is authentic if at least one of a plurality of records in the local header match at least one of a corresponding record in the central directory. The local header may be located in the file archive using an offset specified in the central directory. Moreover, the disclosed systems and methods may include determining that the local header is valid and recovering item data associated with the local header if the local header is authentic and valid.
