AES key wrap

- -

A preliminary implementation of AES Key Wrap, RFC 5649 flavor, using -Cryptlib to supply the AES ECB transformations.

- -

aes_keywrap.py contains two different Python implementations:

- -
    -

  1. An implementation using Python longs as 64-bit integers; and

    2. -

  2. An implementation using Python arrays.

    3. -
- -

The first of these is the easiest to understand, as it can just do -(long) integer arithmetic and follow the specification very closely. -The second is closer to what one would do to implement this in an -assembly language like C.

- -

aes_keywrap.[ch] is a C implementation. The API for this is not yet -set in stone.

- -

All three implementations include test vectors.

- -

The two implementations based on byte arrays use shift and mask -operations to handle the two numerical values ("m" and "t") which -require byte swapping on little endian hardware; this is not the most -efficient implementation possible, but it's portable, and will almost -certainly be lost in the noise under the AES operations.
