Cryptography project

• application uses Windows NTFS to create its own file system
• users can register, login, upload and download files (from/to NTFS), create, view, modify and share files with other users
• private files are encrypted with symmetric encryption
• shared files are also encrypted with symmetric encryption but symmetric keys are stored in digital envelope by using asymmetric encryption
• interaction is pretty bare-bone and is done with console
• amateur simulation of certificate authority is present
