I think that I'd have reached the stage where you can test my code, but
still lacks some basic checks and is still prone to timing attacks and
is basically the same viffs current implementation, with some additional
speedups. So consequently, it code should only be used for testing purposes
I'm achieving the following speeds on my atom N270 ( 1.6Ghz ) testing
with key sizes of 2048 bit.
10 loops, best of 3: 4.42 sec per loop
10 loops, best of 3: 925 msec per loop
10 loops, best of 3: 496 msec per loop
10 loops, best of 3: 143 msec per loop
For encrypting its almost a 9 fold speedup and for decrypting 6.5 times
with respect to the current implementation.
In the tar ball you find the small makefile as well as a test.py file.
It shows the basic use of all functions. If you have any comments, issues
or questions please let me know.
