Hello. I'm an undergraduate student studying electrical and computer
engineering at the NTUA.
As part of an Operating Systems course, I worked a bit on the cryptodev
module, and needed it to use it in a Pyhton project. After searching a
bit on the Internet I couldn't find any cryptodev bindings, so I decided
to develop them myself. I was encouraged by my instructor (Vangelis
Koukis, Cc:ed) to develop the bindings to something more general, that
supports the whole cryprtodev module.
I have created two types of bindings. Static bindings and semi automated
bindings. Static bindings are created based on cryptodev.h and ioctl.h
(from my Linux system). Semi automated bindings are created using
ctypesgen for python. I have created a simple makefile in which
ctypesgen is used to create ioctl.py and cryptodev.py automatically into
a Python module. The reason that I could not build fully automated
bindings is because of a bug in ctypesgen, in which it cannot parse
"sizeof" if the argument is defined in a different header file. You can
see a more detailed explanation in README.md of the ctypesgen branch on
my repository under "Why not fully automated way?" (links provided at
the end). Also I have implemented some of your tests into Python that
use the bindings.
If you are interested, I would like to get this code included in
mainline cryptodev. All my changes currently live at
https://github.com/tchar/cryptodev-python/.
Also the link for README.md, which explains the ctypesgen bug I
mentioned is
https://github.com/tchar/cryptodev-python/blob/ctypesgen/README.md
The link for the ctypesgen module is https://code.google.com/p/ctypesgen/
Looking forward to your comments,
Tilemachos.
