    The key container could not be opened. A common cause of this error is that the key container does not exist. To create a key container, call CryptAcquireContext using the CRYPT_NEWKEYSET flag. This error code can also indicate that access to an existing key container is denied. Access rights to the container can be granted by the key set creator by using  CryptSetProvParam.
