Speck-128/128 in C and PowerPC assembly

This is an implementation of the Speck cipher, with 128 bits key and block size, in C, 32-bit PowerPC assembly, and 64-bit PowerPC assembly.

Disclaimer: This is experimental code, use it at your own risk.

How to build

Ensure that you have make installed, then run:

make main       # Build the C version
make main-ppc   # Build the 32-bit PowerPC version
make main-ppc64 # Build the 64-bit PowerPC version

How to run the tests

After building, run the executable generated (main, main-ppc, or main-ppc64).

TODO

• Does the assembly code work on little endian PowerPC CPUs?
