怎么用CryptGetUserKey获得会话密钥
怎么用CryptGetUserKey获得密钥容器里的会话密钥？
MSDN的描述：
Additionally, some providers allow access to other user-specific keys through this function. For details, see the documentation on the specific provider.
不知道WIN7上那个CSP提供了这个功能？非WINDOWS自带的CSP就不需要了。
怎么让导入到密钥容器里的会话密钥永久保存在密钥容器里？
CryptDestroyKey是这样描述的：
If the handle refers to a session key, or to a public key that has been imported into the cryptographic service provider (CSP) through CryptImportKey, this function destroys the key and frees the memory that the key used. Many CSPs overwrite the memory where the key was held before freeing it. However, the underlying public/private key pair is not destroyed by this function. Only the handle is destroyed.
