The Lass.exe process handles four main authentication services in Windows: Some Windows users find that the Lsass executable consumes a lot of system resources and suspect lsass.exe of being a virus or another type of malware. The certificate has associated private key, but private key property is EMPTY!!! Fun Facts about the name Cng. Just reissued the certificate. For example, middle ages Vigenère cipher was much better than Caesar cipher. CNG may reject an application of a former customer who is indebted to CNG. given a file name in C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys\ or C:\Users\\AppData\Roaming\Microsoft\Crypto\RSA\\, find which certificate is associated with this key(container)file? For sure, you can use certutil: plain and simple. $searchDirectories = @("Microsoft\Crypto\Keys","Microsoft\Crypto\SystemKeys") [Parameter(Mandatory=$True)][boolean] $IsCNG uint dwLegacyKeySpec, The service stores and uses long-lived keys in a secure process complying with Common Criteria requirements. The code example shows how to get the value for the Current User certificate store. $machineKeyDirectory = Join-Path -Path $([Environment]::GetFolderPath("CommonApplicationData")) -ChildPath $searchDirectory If provider type is "0" (which was not a legal value in the old API) it indicates that the provider specified is actually one of the new CNG providers.
