Connect with Friends and Family

Retroshare establish encrypted connections between you and your friends to create a network of computers, and provides various distributed services on top of it: forums, channels, chat, mail... Retroshare is fully decentralized, and designed to provide maximum security and anonymity to its users beyond direct friends. Retroshare is entirely free and open-source software. It is available on Android, Linux, MacOS and Windows. There are no hidden costs, no ads and no terms of service.

Dji-firmware-tools-master Official

A standout feature of the o-gs/dji-firmware-tools (often referred to by the folder name dji-firmware-tools-master) is its comprehensive firmware extraction and manipulation capabilities, specifically the ability to bypass official restrictions like "anti-rollback".

Unlike official DJI software, this community-driven toolkit allows advanced users to interact with the raw components of drone software. Key Capabilities

Module Extraction and Packaging: Using the dji_fwcon.py tool, users can extract individual modules (like the flight controller, camera, or gimbal) from a standard DJI .bin firmware container. It also allows users to merge these modules back into a custom firmware file for flashing. Dji-firmware-tools-master

Bypassing Anti-Rollback: The tools allow for modifying specific data within firmware files to reset the "anti-rollback" counter. This is essential for users who want to downgrade their drone to an older firmware version to regain features that may have been removed in official updates.

Deep Hardware Calibration: The toolkit includes specialized scripts like comm_og_service_tool.py for performing advanced hardware calibrations that are not always available in the standard DJI Fly app, such as fixing off-center gimbals on the Mavic 2 series. Advancing drone capabilities: Beyond the limitations set by

Ambarella Partition Management: For older models using Ambarella processors, scripts like amba_fwpak.py allow for extracting and rebuilding partitions, providing access to the drone's internal filesystem.

The Future of Drone Technology

The dji-firmware-tools-master repository represents a significant advancement in the accessibility and modifiability of drone firmware. As drone technology continues to evolve, the ability to customize and understand firmware will play a crucial role in:

  • Create a decentralized social sharing network designed with no dependencies on any corporate system or central servers.
  • Favor the use of strong cryptography in daily communication.
  • Allow people to hide information from intelligence agencies and spying companies.
  • Favor freedom of speech, away from any possible censorship.
  • Stay independent from corporate systems and centralized servers (Central services might shut down or change their terms of services at any time. Do you remember Myspace? Or German Studivz? Remember when Facebook changed their terms of service? Skype being bought by Microsoft?)
  • Stay a free and open-source software. Only open-source software can provide truly secure communication. Developers can read Retroshare's source code and check that it is doing what it says.

Blog post: Ideals behind Retroshare

How does it work?

Retroshare allows you to create a network of computers (called nodes). Every user has it's own node. The exact location (the IP-address) of nodes is only known to neighbor nodes. You invite a person to become a neighbor by exchanging your Retroshare certificates with that person.

Links between nodes are authenticated using strong asymmetric keys (PGP format) and encrypted using Perfect Forward Secrecy (OpenSSL implementation of TLS).

On top of the network mesh, Retroshare provides services to securely and anonymously exchange data with other nodes in the network beyond your own friends.

Seems too nice to be true. What's the catch?

There is no catch. Retroshare is provided free of charge and does not generate any kind of money. It is the result of hard work that is only driven by the goals of providing a tool to evade censorship.

The only catch is that you will need to build your own network: in order to use Retroshare, you have to recruit friends and exchange certificates with them, or join an existing network of friends.

About

Retroshare was founded by drbob in 2006, as a platform to provide "secure communications and file sharing with friends". Since then other developers joined and steadily improved the software. Retroshare v0.6 is a new milestone which is based on experience from previous releases. A remarkable new component in Retroshare v0.6 is the generic data transportation system (internally named GXS) which abstracts the distribution of authenticated data throughout the network. On top of GXS, Retroshare provides distributed forums, movie channels with comments, and asynchronous messaging.
