Zx8 Stream Cipher: Benchmark Results
Testing zx8 (ps) against RC4 and ISAAC reveal that the output of byte per
second is slower, as expected. This is due to the fact that RC4 has fewer
operations per output byte and ISAAC output 4 byte at once.
These are my results, were each cipher has to complete 3.000.000 runs
genereating 1024 byte each run.
