-
- 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.
