ahh sorry i misunderstood.
for me, encrypted or not, it just goes to whatever normalization is proper for the data;
Basic normalization considerations for me would be:
data is 1:1 and rarely null, same table probably, especially if it will be typically queried witht eh main data.
data is 1:1 with lots of nulls , a separate table for optional data
data is 1:M, then separate table, obviously
HOW it is stored , ie encrypted or not,isn't going to affect that decision, but i can understand how you'd think there is a logical reason to store encrypted data together.
