SECURE INGRESS AND EGRESS OF DATA FIELDS THROUGH LEGACY COMPUTER SYSTEMS

Abstract:

Aspects include receiving an outbound payload for output to a requestor as part of a response to a call by the requestor to an application programming interface (API). Clear data in the outbound payload is selected for encryption based on policy information. The clear data is encrypted to generate encrypted data, and the encrypted data is inserted into the outbound payload in place of the clear data to generate an updated outbound payload. The response, including the updated outbound payload, is sent to the requestor.
