I have a website that displays client info. Their info is stored in a MySQL Database and only the logged in user's info is displayed to the user that is logged in. My site is built on top of Drupal.
I need someone to program an UPLOAD function that will take a CSV and put the data into the Mysql database while ENCRYPTING only two of the 10 columns. Then it needs to be decrypted for viewing. Only the client that is logged in should see the decrypted data.
In other words, the data must be shown to the client in clear text and uploaded in clear text, but STORED on the database as an encrypted hash.
