BSLPOPUP : encrypted message system on LANs

BSLPOPUP use 128-bit key material with the PC1 algorithm
to exchange securely on a LAN ( local area network ), messages
between computers.
You can send attachments too.

Even a sniffer intercepts the packets on the LAN, no one, but 
the receiver will be able to read the message or the
attachement
