You surely have AES.  (The 128 denotes the version with a 128-bit key.)
If you don't have counter mode, I'd be a little surprised, but it's
really easy to do yourself.  See ctrmode.c in the toolkit source.

http://www.tcs.hut.fi/~helger/papers/lrw00/ is a good paper about it,
including a section which describes it in detail.
