Decrypting an encrypted file in memory and then opening it
Posted on 2006-06-20
i have encrypted a file on the hard disk, i want to decrypt this file in memory and want to open it by another application,FOR EXAMPLE suppose that i have encrypted an Excel file so i want to decrypt it in memory and i want to open it by excel , because of security reasons(preventing some usesr from reading it's data) i don't want to put decrypted file on the hard drive so i need it to be decrypted then to be opened only in memory, how can i do this ? I know that excel files can be password protected, but this is only an example and the important case for me is to decrypt a file in memory then open it by another application.
please guide me, thank you in advance for your information.
