Abstract
The present invention provides an encryption/decryption approach to protect valuable information from being represented in a clear-text form when an application processes the valuable information. The present invention processes a structured input file to create internal data structures and generates an encrypted output file from the extracted internal data structures. The encrypted file of internal data structures can be decrypted to enable further processing of the valuable information without representing the valuable information as clear-text in memory. Further, the decrypted internal data structures are stored at different locations in memory.
