Encryption not correct

[GoogleCodeExporter]

Hello,

Running teststate, it seems that the GPU is producing wrong results.

I have tested both version 0.1.1 and the tip (revision 36) on both Mac OS X 
10.6 (GeForce 9600M) and Ubuntu (GeForce GTX 480) and I get the same wrong 
results on both, listed below.

Best regards,
Thomas

Hello Thomas, 

What version of openssl are you using?
What version of the Cuda Toolkit are you using?
I ask this because some other users has reported the same issue using version 4 
and above. If you are using version 4, could you try with version 3?

Greetings,
    MRG

I use CUDA Toolkit version 4.2 on both Ubuntu and OS X.

On Ubuntu, OpenSSL is:

OpenSSL 1.0.1 14 Mar 2012

And on OS X:

-DL_ENDIAN -Wall
OPENSSLDIR: "/opt/local/etc/openssl"

I'm quite busy now, but I'd like to try toolkit 3 when I get the time..

Hello Paolo

I've encountered the same problem .I am using CUDA toolkit 6. Have you solved 
the problem with using newer toolkits ?

Best regards
