Hi,
I'm working with Oracle 10G and using DBMS_CRYPTO.ENCRYPT_AES256 to
encrypt some values.
There are two values that I'm encrypting: Number(32) and Varchar(12).
These values will be displayed as part of the materialized view, and I
need to limit the length of a column. I can't have it as
varchar2(2000), I need some manageable length.
I also have to store the encrypted values in a table and I don't want
to make the column varchar2(2000) (since crypto returns raw(2000)).
I'm wondering how can I "guess" the length of my output string so it
can be used in a materialized view and to properly create the table to
hold it. What does it depend upon? Will varchar(200) be enough?
I'm using 256 bit encryption key.
Your help is appreciated.
