Pro-106 & P25 Auto

[BorisG]

Hello,
There is no information about the P25 in the - DB RR in the website over my county.

this are two movies:

1 shows the two channels of the P25 that im able to receive +all the definition that i did for trying to listen to P25 AUTO- P25 Trunking
YouTube - IMG 0462



2 shows what im able to recive, its not something that I am able to define, is it encoding that the radio canot read?

YouTube - 2

On the second video you're definitely hearing P25 encryption.

is there a way to unlock/crack the conversation contents normally? (to understand what that they are saying)

Not legally, assuming you are in the USA. If you are not an authorized recipient of an encrypted transmission, it was made illegal to decrypt it.

If you want to get into trying to break digital encryption schemes, be ready to put a lot of time into the effort. Most modern encryption systems have the capability to OTAR, which means they can change the key used for the encryption when the user wants to. It will take a significant amount of resources to crack just one key, which might only be in use for a week.

If you want a little insight on how much time/effort that can take, check out distributed.net: Node Zero. This website is the central point on a (legal) effort to break RCS encryption. It shows how long the past cracks have taken, and how much relative computing power that equates to. Then keep in mind that there is, most likely, a triple encryption on the system you are listening to. (I'm assuming it is a Motorola system, which is probably using DES3.)

Basically, yes it is possible, but will take a LOT of work, and might get you arrested.

Illegal? Really? Good to know! Leave!
