just run the sketched aftel loading the libraries.

Raspberry pi

install

sudo make install

Issue 09/09/2006

This is an AES implementation that uses only 8-bit byte operations on the cipher state (there are options to use 32-bit types if available).

The combination of mix columns and byte substitution used here is based on that developed by Karl Malbrain. His contribution is acknowledged. */

/* This version derived by Mark Tillotson 2012-01-23, tidied up, slimmed down and tailored to 8-bit microcontroller abilities and Arduino datatypes.

The s-box and inverse s-box were retained as tables (0.5kB PROGMEM) but all the other transformations are coded to save table space. Many efficiency improvments to the routines mix_sub_columns() and inv_mix_sub_columns() (mainly common sub-expression elimination).

Only the routines with precalculated subkey schedule are retained (together with set_key() - this does however mean each AES object takes 240 bytes of RAM, alas)

The CBC routines side-effect the iv argument (so that successive calls work together correctly).

All the encryption and decryption routines work with plain == cipher for in-place encryption, note.
