A compressed KPA package is a file in KPAC format. KPAC format is a variant of the ZIP format but with the following limitations: no directory hierarchy, no embedded ZIP archives, and a limit on the size and quantity of its archived files. A KPAC file contains a KPA package, its external signature, and an index file. The external signature of a KPA package is a file in the proprietary KCAT format that resides outside of the KPA package file. The external signature protects against spoofing and modifications of the KPA package itself and the index file of the KPA package. The index file of a KPA package is a file in the proprietary KIDX format that is used to check the integrity of the KPA package.
