Sanjay,

If you appent a new row to the table and type data into those columns, does
it remain as entered?  AFAIK, MS Access has no tool that would selectively
allow columns to be encrypted.  However, I can easily think of several MOL
trivial ways to accomplish this.  The table could be processed by a query
that calls an encryption routine written in, say, VB.  Or, cruder but
equally effective, the column content could be exported to a text file,
processed by any number of encryption products (e.g., PGP), then read back
into the table, overwriting the original content.  How badly do you need to
know what is in those columns?  Has there been a risk assessed for not
doing so?

Recently a consultant at one of our clients got let go under not so good
circumstances. We were called into see if he had left any backdoor behind.

We did not find any backdoors but we found out that he encrypted two
columns
of data in a access database. The data in the columns look like this

We cant figure out how he encrypted it. Has anyone seen this before?
