This is a small and portable implementation of the AES ECB and CBC encryption algorithms written in C.
You can override the default 128bit key with a 192 or 256bit by defining the symbols AES192 or AES256 in `aes.h`.
The API is very simple and looks like this (I am using C99 `<stdint.h>`-style annotated types):

You can choose to use the standard 128b key or 192/256b by defining the symbols AES192 or AES256 in `aes.h` - AES128 is defined by default.
You can choose to use one or both of the modes-of-operation, by defining the symbols CBC and ECB. See the header file for clarification.
