You might need to uninstall antivirus (in my case I had to get rid of Avast).
This makes sure that crypto::cng
command will work. Otherwise it was giving me errors:
mimikatz $ crypto::cng
ERROR kull_m_patch_genericProcessOrServiceFromBuild ; OpenProcess (0x00000005)
After removing Avast:
mimikatz $ crypto::cng
"KeyIso" service patched
Magic. (:
Windows Defender is another program blocking the program to work, so you will need also to disable it for the time of using program at least.
