I had released, a long time ago, code to use AquaticPrime for license verification. That code was using native crypto libs on both macOS and Windows. The Windows code was 32 bit only, though.
I wonder if anyone has updated that code to use the built-in crypto functions so that it works on Windows 64 bit, too?
The bdrister github code is like 8 yo now. All the forks look untouched, except your effort trying to update it to current Xojo. So my guess is that right now you may be alone in the effort.
Thank you for looking into that for me. I was just in the middle of releasing an update to Arbed when I realized that Arbed for Windows is still 32 bit only, just because of this part. Hoped for a quick solution, but then, 32 bit apps still work fine on Windows, it seems 
Also, not sure if anyone but me and Beatrix still uses Arbed, let alone on Windows or Linux.
I do remember suffering some problem due to a code being 32bit and the solution was converting it to 64bit. So the 32bit version is kinda deprecating now.
I do on macOS for debugging problems posted here!
Still using Arbed here, both on Windows and MacOS.
It’s been a real help showing the diffs when using svn
