| Hi Florin

| A consideration here is whether you want to be able to de-code the data.

| An example is a users table, which contains an encrypted password. You

never

| want to decode the password, you want to compare the encrypted users

| password against the value stored - a one way street, in other words.

| To do this you can use sys(2007) to generate a checksum of the values,

which

| you can store in the table.

| If you are going to want to decode the stored data, use something like Dae

| suggested, which is secure but easily reversed. There is a reversible

| encryption library out there somewhere (Tom Rettig's CIPHER.FLL?) if you

| want something a bit meatier.

| hth,
