Unfortunately, with the encryption string being limited to alphanumeric
characters, a short string would probably be indicative of a very weak
encryption routine.  In other words, the fewer characters you allow as
encryption output, the longer the string has to be for reasonably strong
encryption algorithms.

Of course, hexadecimal ignores about 77% of the alphabet, so if there's
an option that allows use of the entire alphabet (rather than rendering
as hexadecimal), you should be able to get shorter strings.
