Hello all, I have two questions about encryption on DMR, I understand all the rules regarding not using it on Ham bands. I first am curious about how easy it is to crack 40-bit encryption; I understand I could go for an expensive AES-256 but that is not the best option. How easy is it to crack DMR encryption? I am unaware of any higher security then 40 that is available cheap. In the past they have cracked 40 bit in 22-56 hours, I'm guessing that will be much easier considering what government agencies have now, could any average or advanced Ham listener crack it now? Does anyone have any recommendations on higher security then the HD-1 40 bit? Thank you in advance for informing me more on this.

To anyone looking to acquire commercial radio programming software:
Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity.
If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request.
To obtain Motorola software see the Sticky in the Motorola forum.
The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.
For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).
This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.

Check out Louis-Erig Herve on YouTube. This will answer you questions really fast
Thank you I will check that out
Despite fake youtube videos, no one bothers as its not a thing. Its claimed to be easy and yet , even radio hacker Travis Goodspeed has admitted its too time consuming. There is software called openear which claims to do this for extortionate money but dosnt. No one will be able to listen to you. The more important question is do you have a licence for the frequencies you are using?

The question I always have to ask is: Who is it that you don't want knowing what you are talking about? If it is just some others who might be on the same frequency, or you don't want your wife overhearing what you say to your girlfriend, don't worry. Yes, it is possible to break 40 bit encryption. But, it isn't all that easy, and almost no one you will encounter in everyday life has either the will, or ability to do it. If you fear the NSA, well that's another thing, and you should be looking at much more than just what you say on the radio.
Updating your keys regularly helps thwart things as well.
If you look at the Anytone radios they come with AES-256.

Change keys on a regular bases, and you will be fine with 40-bit. The effort needed usually slows all but the most dedicated. And what you want to talk about amongst yourself and friends is no ones business but your own.
The inquisition I see has already begun, so wear a helmet

Using DMR at many sites across the nation, I now use 900 MHz Motorola DTR series radios when I really do not want to be heard, or hear anyone else. I am glad that Trbo series radios have a form of privacy settings though. Interesting topic and discussion. I admit, even on my Garmin Rino 530's, I use speech inversion all the time with the people I talk with.
