Access Data Encryption Seminar
By Richard Rost   Richard Rost on Twitter Richard Rost on LinkedIn Email Richard Rost   9 years ago

Access is a great database program, however one of the problems with it is that you can't really secure your data very well. Unless you have a database server (like Microsoft SQL Server) this is a problem for sensitive data. You can lock up your forms, reports, and VBA code (and I show you how in my Security Seminar), but the data is still out there unprotected.

In this seminar, I teach you how to lock down the data in your tables so that nobody can see your private information unless they're allowed to. Scramble & encrypt sensitive data to keep it from prying eyes. This is a good solution for securing data without the need for an expensive database server platform. You'll learn how to:

1. Scramble data in your tables to hide sensitive information
2. Convert text characters to their ASCII equivalent values and back
3. Perform mathematical obfuscation on your data
4. Control access to the form that handles the encryption / decryption

I think at one point you suggested to use a make table query to load the decoded data into, use it for whatever purpose then destroy that table when done, right?

Rick,

Will queries and functions that depend on data in encryted tables be able to use this data or will it have to be decdoded before using it?


Reply from Richard Rost:

You'll have to decode the data before ANYTHING can use it, which is why you need to take specific care to decode each record as you load it into a form. It's not a perfect solution, but it's the best solution available for JUST Access. Read More...

Hi Richard,

I trust you are well.

I've just worked through this seminar and built the sample database. Fab! Most enjoyable. I alse made the Encryption Module (Public function global); made an Asset Register form with a lot more values and encrypted quite a few fields. Had to include an On Error Resume Next 'handler' in  the code and it works just fine. My question as follows: how could I set up a continuous form to display all the de-encrypted data for a report printout and then encrypt all the records in one go. I've tried this and the form only shows one record. I know I'm still a novice' Access student but if this is possible, I'm sure there must be more of us out there that would love to know how to do this. Read More...

There is a TON more you could do with this concept. For example, in one of my databases, instead of using a set of 2 keys to encrypt the database, I actually use a whole PASSWORD so that the data gets changed based on a rotating list of values (the ASCII values of the letters in the password). It makes it VERY difficult, if not impossible, for anyone to decrypt. If anyone wants to see this, let me know. If enough people post here, I'll make an add-on video.

My sample database has been uploaded to the Student Database Folder. You can grab a copy if you don't want to type in all of my code, although I do recommend you TYPE IN THE CODE as I build it... you'll learn better that way. The file is password protected. As a reminder, you can find the password by logging on to your account and looking at your course listing.
