This book is about the OpenPGP support available in the Encryption Facility for z/OS V1.2 (Program Product 5655-P97). It begins with a discussion of the principles of operation of the OpenPGP protocol and a review of some basic cryptographic topics. It presents detailed steps for installing and configuring Encryption Facility for z/OS and implementing OpenPGP support.

Practical examples from our lab and from the authors’ real world experiences demonstrate how to set up and use the capabilities of OpenPGP support. The options available within the product are discussed, and recommendations for appropriate selections within the context of your intended use are offered.
