cryptodev support

cryptodev support

[Nikos Mavrogiannopoulos]

Hello,
 I needed to access crypto hardware modules from userspace and I made
that by adding cryptodev support on top of linux-crypto. It is a
separate module available at:
http://repo.or.cz/w/cryptodev-linux.git

It was originally based on the old cryptodev module found at
http://www.logix.cz/michal/devel/cryptodev/

In the extras directory there is a patch for openssl that will make use
of the /dev/crypto. Gnutls (2.9.x) will use /dev/crypto if it compiled
with --enable-cryptodev.

regards,
Nikos

I'm also interested in the userspace module (we are working on a patch
for opencryptoki), but this version looks quite different from the ideas
"recently" discussed in this mailing list and, probably even more
important, from the idea for future development (i.e. moving to a
socket-like interface).

Couldn't be useful to start discussing (read: receive directives) and
officially introduce cryptodev in linux-crypto, instead of losing so
many energies?

Best,

I'm not aware of the discussion in the ml. I don't argue that this is
the only way to expose the internal API to userspace. It is one way that
few other OS's support as well. For this reason it is the best from the
user-space developer point of view to have a single API across many OS'.

This is really good, in my opinion.
What the others think?

Hello,
 For anyone interested in the /dev/crypto for linux I've setup a website
and made a beta release of the cryptodev module. It can be found at:
http://home.gna.org/cryptodev-linux/
