Hello Björn,

thanks for the information. Your package didn't turn up on Google when I started with my experiment. Perhaps it's too new?

Your code and mine have lots of similarities. I was amused when I saw that you had the same issue with the block size attribute. At first I set it to 200 (1600 / 8) but eventually I didn't implement it.

My code does everything in C with a separate constructor for each flavor of SHA-3. It's compatible to Python 2.6 to 3.4 and uses the optimized code for 32 and 64bit platforms.

Oh, and my code is now working properly. Feel free to review the module. I'll upload the test code later.
