From the developer:
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.
You may want to check out more software, such as Kaspersky Security for Microsoft Exchange Server 2003, SC Spy Message or Encrypt My Information, which might be similar to ShareCrypt.
