Ah I missed that the last round of output had the initialization call patched out. Reading through again, if the key is in the local computer store vs. the current user store, then it looks like the call to NCryptOpenKey (inside privkey_import_ncrypt on line 710) needs to have flag NCRYPT_MACHINE_KEY_FLAG passed as the last parameter (https://docs.microsoft.com/en-us/windows/win32/api/ncrypt/nf-ncrypt-ncryptopenkey) to succeed but right now it's hard coded to 0.
Windows API error codes are negative when interpreted as a signed integer so ret < 0 is failure.
