A guid is always 16 bytes. So you could grab the 16 bytes and encrypt
those.
I think what you're working with is an ASCII representation of those
bytes, in HEX. When databases don't support a varbinary
type of guid type to store the 16 bytes in, you're doomed to use the ascii
representation.
WHat's odd is that 16bytes in hex is always 32characters tops. So it's
beyond me why they reserved 30 positions, not 32. 30
positions for a guid is absurd and not enough to store the value.
