Glenn,

You won't be able to encrypt just one table - it's the whole database or
nothing
with SQL Server CE. Some options for you:

1. if that table has no constraints that would prevent this, place the
table by itself in a second
SQL CE database and encrypt that database. switch connections in your app
between the
two databases.

2. use a simple encryption/decryption algorithm on sensitive column data
when you
load/query the table. a sample is attached in C# (assuming you are using
the Compact
Framework). Credit belongs to Paul Yao for offering this class in his
outstanding book
".NET Compact Framework Programming with C#"
