How to build this project to use the 32bit library instead of 64?

I am wondering if there's a way to use the win32/cryptoki.dll instead of the 64bit cryptoki.dll by default.

If you're using 32b python, it should automatically use the 32b library referenced in the crystoki config files (LibUNIX in Chrystoki.conf for linux, LibNT in crystoki.ini for windows).

Alternatively, set the CRYSTOKI_CONF_DLL environment variable to point directly to your dll/.so path.

Hi @astraw38,
I've tried using 32b python and I am using the win32/cryptoki.dll by changing the cryptoki.ini. I still get this error.

You'd need to use 32b python to load the 32b dll (ref)
