- I don't know of-hand of a way for INGRES to do encryption, but you can write
- your own datatype that encrypts the data for you. This is possible using the
- Object Management Extension (OME). With OME, you actually construct the
- datatype, including writing code for comparison of two values, adding,
- subtracting, etc., hash key generation, and other things. For this problem,
- you could construct the datatype to perform encryption of input values before
- the value is stored to the database. Whenever the value is needed for output,
- comparison, adding/subtracting, etc, then your code would decrypt the value
- first.
