ShareCrypt - Version 2.1 ShareCrypt has been designed to effectively and transparently encrypt shared network drives or folders by allowing simultaneous data access to different users and preventing unauthorized access from non-authorized people. ShareCrypt is very easy to use and it encrypts data with strong encryption algorithms such as AES 256 bit and Blowfish 448 Bit. ShareCrypt is a client-based concept: A client user sets an encrypted shared folder/disk and defines other users access level by setting up additional passwords. Everyone with a valid password can read or write data on the encrypted shared disk even simultaneously
