推荐答案

阅读完评论后，问题应该更新。



这个答案是针对Windows的。



您可以创建具有独占读取和独占写入权限的临时文件，并在应用程序关闭时设置要删除的文件。

使用零作为共享模式（不包括）。包含标志参数的FILE_FLAG_DELETE_ON_CLOSE。



在应用程序运行时保持文件处于打开状态。在关闭文件之前，擦除文件内容。



这不是100％，但涵盖了大多数情况。如果在文件存在时设备断电，则数据仍然存在。



一个更好的解决方案（虽然不是你原来的问题）只是解密所需的部分并将它们保留在内存中。

After reading through the comments, the question should be updated.

This answer is Windows specific.

You can create a temporary file with exclusive read and exclusive write access AND set the file to be deleted when closed by your application.

See this link:
http://msdn.microsoft.com/en-us/library/windows/desktop/aa363858%28v=vs.85%29.aspx[^]

Use zero for share mode (exclusive). Include FILE_FLAG_DELETE_ON_CLOSE for the flags parameter.

Leave the file open while your application is running. Just before you close the file, wipe the file contents.

This isn't 100% but covers most cases. If the device is powered off while the file exists, the data is still there.

A better solution (though not your original question) would be to decrypt only the portions needed and retain them in memory.
