Note transmission security
StickyNote transmits your notes via the protocol of your network when you send a note from your computer to another directly. StickyNote serializes your note, the same procedure it uses when saving a note to a file, and then pushes it over the network to its destination.
StickyNote also uses Tenebril's proprietary encryption algorithm before sending the note; as a consequence, the content of your note will not be obvious to anyone who has hacked into your network's trasmission system.
However, because this encryption format is used by StickyNote in reading the file, a serious hacker could work around the encryption system. This procedure is extremely complicated and very painful. It would be a grand waste or resources to try to capture someone’s StickyNote transmissions.
But it is possible. Therefore we suggest you not send your credit card number, highly sensitive personal information or items of national security through StickyNote notes. In general, however, it is quite safe for daily chatter. The procedure is complicated enough that coworkers can’t read the notes you send to your friends; people can’t just fire up a secret program and read all the notes you send. But to be fair, as has been said, it is possible.
