Re: Data Encryption + interactive upgrade

Hi Chris,

You actually have Triple DES APIs in your Alliance FTP Manager library that
you can use for encrypting fields in a database file. The APIs are being
used for some fairly high volume database requirements. Triple DES is
accepted by Visa, HIPPA, and others for securing data. Of course, encrypting
fields that are keys represents a bit of a problem. The key value is
predicable after encrypting, but your query tools won't be of much use. It's
better to arrive at a mechanism for keys that does not involve sensitive
data.
