In macOS you need to codesign your application.
After running the registration application the new file "nist_license_64.key" will be created.
You need to copy file "nist_license_64.key" to the same folder where "libNIST_library_macOS_x86_64.dylib" is located.
Make sure that files "nist_license_64.key" and "libNIST_library_macOS_x86_64.dylib" are located in the same directory.
After placing new file "nist_license_64.key" into your application folder, you need to codesign anew your application.

====================================================
For distribution outside App Store:

codesign -f -s "Developer ID Application: Name Surname (1234567890)" -v "nist_demo.app" --deep


Alternative codesign command:

codesign --force --deep --verbose --sign "Developer ID Application: Name Surname (1234567890)" "nist_demo.app"
====================================================
How to check codesigning:

spctl --assess --verbose --type execute "nist_demo.app"


Alternative check codesigning command:

codesign --verify --verbose "nist_demo.app"
