Hi Julia,

See Question 18 at http://csrc.nist.gov/CryptoToolkit/aes/aesfact.html

Also, Wei provides it in the library:

/// seckey.h
/// support query of variable key length, template parameters are
///   default, min, max, multiple (default multiple 1)
template <unsigned int D, unsigned int N, unsigned int M, unsigned int Q =
1,
          unsigned int IV_REQ = SimpleKeyingInterface::NOT_RESYNCHRONIZABLE>
class VariableKeyLength {
...

and

/// rijndael.h
struct Rijndael_Info : public FixedBlockSize<16>, public
VariableKeyLength<16, 16, 32, 8>
{
        static const char *StaticAlgorithmName() {return "Rijndael";}
};
