Note Safe is a very secure storage tool, allowing you to store notes, passwords, and other data in a secure way. The tool is built up on multiple layers of security. Its main interface is via the Wolf Software Secure Portal, which only allows people with registered accounts access to the system. You can only access notes that you created. Finally, each note is encrypted with a user-supplied password using mcrypt. The password is never stored and it is combined with a site wide key in order to create the final encryption key.
