Hello @yonas, could you paste the output of lscpu or cat /proc/cpuinfo to see what your CPU model is and what features it supports?

Unfortunately it seems you CPU does not support AES-NI instructions https://www.intel.com/content/www/us/en/products/sku/41447/intel-core-i7930-processor-8m-cache-2-80-ghz-4-80-gts-intel-qpi/specifications.html

Gxhash currently does not has a fallback, but you can look for the presence of AES feature at runtime to switch between Default / GxHasher depending on machine capabilities.

Thanks, hopefully I'll upgrade my computer soon.
