In particular I can't retrieve a key cryptacquirecontext failed error container which is already defined. I use the CryptAcquireContext() function. I use some test code where I create the container. Then If I go to C:\Users...\Roaming\Microsoft\Crypto\RSA\Machine Keys\ I can see a file created with my defined container name inside so I assume it's created successfully. A subsequent call to try creating the same container verifies that assumption because I get the win32 error that the keyset is already defined. Anyway on my next code call where I try to retrieve the container I already created I get the windows error that the keyset is not defined. Error : -2146893799 (80090019) The keyset is not defined. Any ideas? Here's a code example : public const uint PROV_RSA_FULL = 1; public const uint CRYPT_NEWKEYSET = 0x00000008; public const uint CRYPT_MACHINE_KEYSET = 0x00000020; const string MS_DEF_PROV = "Microsoft Base Cryptographic Provider v1.0"; [DllImport("advapi32.dll", SetLastError = true)] [return: MarshalAs(UnmanagedType.Bool)] public static extern bool CryptAcquireContext(out IntPtr phProv, string pszContainer, string pszProvider, uint dwProvType, uint dwFlags); public static void CreateContainer() { IntPtr hCryptPr
