The branch, master has been updated
via 77d88d7 Allow AESNI to be used on all processor supporting AESNI,
not just Intel's This improves performance/reduced CPU usage. Tests performed:
- Ran on Ivy Bridge and Ryzen and verified that AESNI is detected (crypto
tests) - Ran on Ryzen, and observed 50% increased speed.
