Subject: [oc] DES cores
I've tried to verify the results of the three available DES cores to
software implementations without any luck. I wrote software in C, C++
and Java using various techniques and libraries and these three
methods produce repeatable results. However, I modified test benches
to input exactly the same keys and data for the RTL, but cannot
correlate the results.
I've been very careful about transposing my data between the software
and hardware syntax, i.e.
sw: char key[] = { 0x34, 0x56, 0x23, ...};
hw: key = x"...23 56 34"
Has anyone verified the results of the encryption cores with software?
Any idea what I might be doing wrong?
Chris
