How to export and import plain text session keys by using CryptoAPI

Sometimes it is convenient to export and import plain text session keys. However, the Microsoft Cryptographic Providers (Base and Enhanced) do not support this feature. Both CryptExportKey() and CryptImportKey() require a valid key handle to encrypt and decrypt the session key, respectively. But by using an "exponent-of-one" private key the same effect can be achieved to encrypt and decrypt the
