This is an effort to reverse-engineer the Raspberry Pi license key check forMPEG-2 and VC-1 hardware video encoding.

Patch

Click on the server classes tab - Click add a new server class - on the clients side, add your raspberry pi host - on the apps side, add the app or apps that you want to send to the pi - CLick save. On the next poll from the pi, it will notice there is a new app to deploy to it, pull it from the deployment server and then install it on the pi. It would be best & the most secure if you wrote a short script that could generate a keypair on each raspberry pi and then copied the public key to the server (e.g. This way your private keys are on the pi's in the way the system is intended for. It doesn't matter who generates the key's per say, just how they're transported. Add a new page. Now you’re going to add a new page to your web app by creating a new route. In a web application, a route is a certain path into your website, determined by the URL the user types into their web browser’s address bar. It’s up to you which routes are enabled and what each of them does. Mar 14, 2014  Using a Raspberry Pi as a web server is one of the fundamental uses of a Pi. It opens up a number possibilities. The best way to find out what you can do with your new Web Server would be to play around with it, and see what it can do! Passwordless SSH access. It is possible to configure your Pi to allow your computer to access it without providing a password each time you try to connect. To do this you need to generate an SSH key: Check for existing SSH keys. First, check whether there are already keys on the computer you are using to connect to the Raspberry Pi: ls /.ssh.

A patch for start.elf, a firmwware blob for the VideoCore IV processor used byall Raspberry Pi models, was posted toredditby /u/fuck_the_mpeg_laon 03-03-2017:

Applying it to a4.14.44 start.elf(latest as of time of writing) results in the following diff: emaze free download for mac

Yes, it seems to patch a licensing function at 0xEC95FD4 [1] to always return 1,by patching the jump at 0xEC95FE2 (that should be only taken for the always-allowed H263 codec)to always be taken, thus always allowing all codecs.

The initial entry point is disassembled using theVideoCore IV pluginfor IDA Pro 6 by hermanhermitage.

After loading and analyzing start.elf, we can find the is_licensed routineat address 0xEC96290 by jumping to the file offset given to us by xxdbeforehand. The relevant code sections are available insub_EC96290.asm and is_licensed.asm.

Here, two memory locations (0xEE86680 for MPEG-2 and 0xEE869E0 for VC-1)that point to the .bss segment are checked to determine the return value ofis_licensed. There are no other obvious references to these locations instart.elf, so memory-breakpoint debugging (TBD) is probably needed.
