FWIW, I have two more test results from Windows machines with Intel CPUs: - i7 8750h - i9 10980KK Both are AVX-capable and produce the encrypted sha 6FBEE484EE64A2AB02235DDF29CA0B61EE3B811D227C2729836D3BD6161C9B18. On Friday, September 17, 2021 at 11:31:48 AM UTC-7 austin clifton

Hey Jeff, thanks for the fast response! Yes, the encrypted sha from your AMD CPUs matches what I get on my Ryzen 7 3700X. The encrypted sha from the i7 is 8F16077454F8477594CAD4304126B0A6F30C8C4D2536E2441FFFD320656E1DF1. That's also the sha I get if I disable AVX on my Ryzen when compiling
