cryptverifysignature (advapi32)
The CryptVerifySignature function verifies the signature of a hash object. Before calling this function, CryptCreateHash must be called to create the handle of a hash object. CryptHashData or CryptHashSessionKey is then used to add data or session keys to the hash object. After CryptVerifySignature has been completed, only CryptDestroyHash can be called using the hHash handle.

C# Signature:

[DllImport("advapi32.dll", CharSet=CharSet.Auto, SetLastError=true)]
public static extern bool CryptVerifySignature(
    IntPtr hHash,
    [In] byte[] signature,
    uint signatureLen,
    IntPtr pubKey,
    IntPtr description,
    uint flags);

VB Signature:

Declare Function CryptVerifySignature Lib "advapi32.dll" (TODO) As TODO
