Customizing the Exit

This exit is always invoked by the server runtime before the response is sent to the client. The exit must update TIRNCRYP-RETURN-CODE field to indicate whether the data is encrypted. The data that can be encrypted buffer pointed to by DATA-BUFFER-PTR with length BUFFER-SIZE bytes. Ensure that DATA-BUFFER-PTR points to the location of the encrypted data and that BUFFER-SIZE is updated with the correct data length. The maximum size of the encrypted data cannot exceed ENCRYPTION-MAX-SIZE
