Marco,
> Maybe storing it into a CHAR(22) using OCTECTS charset? While this will work and is the smallest storage footprint/representation. I would recommend to sacrifice disk space and to store the key as a string using a base 36 encoding (0-1 + A-Z) -- it makes debugging via tools much easier. Difference space between OCTET and base 36 encoding would only be an additional 7 characters. Sean
