Encryption and Decryption

For those cooperative flows that use a CFB to exchange view data between a DPC and DPS, CA Gen offers the opportunity to have a portion of the request or the response that is transmitted in an encrypted form.

The use of encryption and decryption can occur regardless of the type of security processing being used (SECURITY_NONE, SECURITY_STANDARD or SECURITY_ENHANCED).

Two sets of user exits are invoked during the processing of a cooperative flow. One set lets the request be encrypted by the DPC and decrypted by the DPS. The other set lets the response be encrypted by the DPS and decrypted by the DPC. The two sets of encryption/decryption user exits can be used independently from the other. That is, the request can be encrypted without having to encrypt the response. The same is true for the response. The response buffer can be encrypted without having to encrypt the request.

Notes:

• For more information about deciding which section of the CFB is eligible to be encrypted, see Common Format Buffer in the appendix "Glossary of Distributed Processing Terminology."
• For more information about the user exits used by the DPC and DPS to encrypt and decrypt cooperative flow data, see "Distributed Processing User Exits."
• For more information about decrypting user exits available for use in these applications, see the Distributed Processing—Client Manager User Guide and Distributed Processing—Communications Bridge User Guide.
