Michael,
I just did something like this, and used the ENCODE/DECODE. Works well.
Basically you want to assign a "special key" for the encoding/decoding of the
data you want to encode/decode. The column type should be either a BLOB or
TINYBOLD, as it's stored in a binary format, depend on the size of the data
being encoded.
To encode the data, you do something like this.
The $key would equal a special value to encode then decode it back, without the
$key, it will not be able to decode the encoded data. Like a password to
encode/decode.
INSERT INTO table_name VALUE
('foo','bar','foobar',ENCODE("$data_to_encode","$key"),'other_data');
Then to retrieve the encoded data,
SELECT DECODE(col_name_with_encode_data,"$key") FROM table_name WHERE something
= 'A_Value';
This is a very simplistic example, but should give you some ideas on how it can
work.
Hope this helps,
