PKWARE Inc

PKWARE, Inc. is the creator and continuing innovator of the ZIP standard for data compression and security, and markets its products under the SecureZIP and PKZIP brands. Since its founding in 1986, PKWARE's mission has been to develop and extend the ZIP standard to meet end-user and enterprise needs for compressing files for efficient storage and transmission. The .ZIP file format is now used by millions of users around the world.

PKWARE introduced PKZIP in 1989, which quickly set the standard for compression on DOS, Windows, UNIX, Linux, iSeries, zSeries, and other platforms. In 2001, PKWARE extended the .ZIP file format to include the ability to add strong authentication and encryption to ZIP archives, making it possible for end-users to not only compress files into a "container" for efficient transmission and storage, but to also secure that container to prevent unauthorized access and modification to the contents.
