Unless IDEA has pathways that make attacks significantly faster than

serious doubt anyone can brute force a 128 bit key. You aren't making
the mistake of believing that a 128 bit key is 64 times harder to break
than a 64 bit key, are you?

If you try *100 trillion* keys per second, and find the key half way
through the keyspace, a 128-bit key will be found in only 5.4 x 10^14
centuries!
