really??? Not to flame you but a bit of background research would tell you that there are no scanners or programs to decode encryption. If there were it would render the use of encryption useless.
Encryption is a reality of scanning today. Many services do not use it and there is lots of activity that can be monitored. My local system is encrypted however by monitoring Fire/ EMS/ Works/ Electricity and specific local users like malls and stores I rarely miss out on calls.
