OK now that I have graduated from iseries SQL encryption 101 (OK the first hour of class anyways):

Is it possible to encrypt a 10 byte character field in place? (Lets assume it was created with FOR BIT DATA).

For example,

TaxFile contains 9 digit SSN.

Is it possible in SQL to:

update TaxFile set SSN=Encrypt_RC2(SSN) to provide an encrypted SSN?

It doesn't seem possible since the receiving field is larger than the source field.

Any ideas or other methods that can encrypt a field in place (without expansion)?

It doesn't seem theoretically impossible (although maybe less secure).
