Description Eric Roman 2014-12-03 23:58:12 UTC 
AES-CTR throws a DataError in its "get key length" operation if the length is not one of {128, 192, 256}.

Whereas the other AES algorithms throw an OperationError in this case.

I suggest using OperationError for AES-CTR to match the others.

I agree that this should be made consistent.  However I believe that DataError would be the correct error returned in this case.  The data provided is incorrect.
