We need to encrypt some of our frequently accessed data files. Some general advice would be great before I begin down the wrong path. In particular, I am wondering about the functional difference between the “REQUIRED FOR OPEN AND ON DATA” and “REQUIRED FOR WRITE AND ON DATA.” I understand the “OPEN” idea, but then is no password required for OPEN and READ for the “WRITE” option?
Impact on performance is a big issue, so I’m wondering about reducing that. Is there an impact using the industry standard versus the native PVX encryption?
The principal file involved already uses a data dictionary for embedded i/o purposes (we record certain accesses to it). Is using the EIO functionality the preferred way to go?
