Included are methods for ECB, CBC, CTR, and XTS modes. They are not

Your code uses the standard algorithm names like cbc(aes), which implies that it
is compatible with the standard cbc(aes).  So which is it -- compatible or not
compatible -- and if it isn't compatible, what is the expected use case?

Yes, it provides AES-CBC functionality. Well, it was intended to avoid mixed
use of functions -- setkey(), decrypt(), and encrypt() -- from others.
Perhaps, rewrite this as:

  Each method should not be used along with other implementations'. E.g., KL’s
  setkey() output can’t be used to the input to the encrypt() method of AES-NI or
  generic implementation.

Thanks,
