This should be so simple, but I have not found any way to do it. Use a certificate based on a key pair generated by a legacy Cryptographic Service Provider. #Does the certificate have a CNG key? If you want the Local Machine store, replace, [void][PKI.Tools]::NCryptOpenKey($phProvider,[ref]$phKey,$keyProv.pwszContainerName,0,0), [void][PKI.Tools]::NCryptOpenKey($phProvider,[ref]$phKey,$keyProv.pwszContainerName,0,$keyProv.dwFlags), The last chunk of 19 line code does not actually output ContainerName. Again, enumerate certificate in the store and check if there is matching public key in certificate. The virus has been around for several years and Microsoft has already taken measures against it. CNG fully supports Unicode key container names; CNG uses a hash of the Unicode container name, whereas CryptoAPI uses a hash of the ANSI container name. It also creates a default CngKeyCreationParameters object that specifies a default CngProvider and other advanced parameters for the key. However, if the key was created outside of the CLR we will need to setup our // ephemeral detection property. However, as David pointed, with new .NET versions, you can retrieve CNG public/private keys directly from X509Certificate2 object. The newer CNG providers do not have provider types. The key description is useful to users who manage multiple keys.
