Re: communicating from the user space

Hi Nikos,

Thanks a lot for the information provided on openssl part for cryptodev-linux.

I have followed the steps mentioned in "
https://github.com/cryptodev-linux/cryptodev-linux/blob/master/INSTALL
"

But When I executed " make check" command I got following error,please
can you help me with this.

cc  -I..    -c -o cipher_comp.o cipher_comp.c
cc  -I..    -c -o openssl_wrapper.o openssl_wrapper.c
openssl_wrapper.c: In function ‘openssl_hmac’:
openssl_wrapper.c:136:5: error: invalid use of void expression
openssl_wrapper.c:144:3: error: invalid use of void expression

make[1]: *** [openssl_wrapper.o] Error 1
make[1]: Leaving directory `/home/srisowj/cryptodev/cryptodev-linux-1.6/tests'
make: *** [check] Error 2

Hi Nikos,

Please can you let me know my understanding regarding openssl and
crypto are correct?
I have mentioned my understanding in my earlier posts,but let me
mention it here again.
I want to interact with Crypto Hardware from user space using openssl
like libraries based applications through cryptodev-linux interface.
it looks like openssl comes with cryptodev-linux support(through
eng_cryptodev.c) .
When I downloaded openssl,eng_cryptodev.c file is available by default.
below link refers about eng_cryptodev.c for openssl support :
http://repo.or.cz/w/cryptodev-linux.git/commitdiff/56cc4e3b8b761cb34f928f4eee59755d1f0afc53

That's a very old link. Note that openssl's cryptodev support works
well for ciphers, but not for digests (hashes). So the best is to
compile without digest support, or use the patches in
https://github.com/openssl/openssl/pull/191

The most current instructions are:
https://github.com/cryptodev-linux/cryptodev-linux/blob/master/INSTALL
and in https://github.com/cryptodev-linux/cryptodev-linux

regards,
Nikos
