#1165 — SEC - Secure Eurasian Communications

Hi all,

SEC will probably not been liked by TLAs or NSO from Israel
and FinSpy from Germany. But I thought of the rise of Eurasia
and BRICS and think that people living there need proper and
super easy to use public key cryptography for Windows and Android,
which outperforms GnuPG on Linux and age.

It will use:

Air-Gap first design - Specifically developed for offline scenarios
QR code bridge - Physical data transfer without network connection
Recovery function - Unique solution for photographed/filmed QR codes
End-to-end encryption - Using state-of-the-art cryptography (NaCl)
No metadata - Perfect privacy
ISO padding - Standardized and professional
Minimalistic design - Easy to use

The CLI version is ready and late I will focus on the GUI vesion.

Recommended hardware:

GPD MicroPC - Windows 11 and Camera app with WebCam (offline usage only)
Android smartphone with PluGMate and Camera2 app

Hope you like!

Quick test with the CLI version:

msg.txt:

Hello world! 😊

sec e -f self -t bob < msg.txt > msg.png

This QR-Code was then photographed with a smartphone,
resulting in a large .jpg image:

https://jumpshare.com/share/mCCk7fVjFsQpdLdoRocB

It was then cropped:

https://jumpshare.com/share/xOW1ytRlwy3zegsTq4b3

And the cropped image was then recovered, so it could
be sent as the original QR-Code image:

sec r < crop.png > msg_recovered.png

https://jumpshare.com/share/egIdFfGBy9MKKYGQyxCd

This workflow, as you can see, is air-gapped and
outperforms GnuPG and age on Linux, to show that
Windows 11, offline usage and as sender an Android
smartphone is the way to go when sending small (max.
344 bytes) important messages, as encrypted NaClbox
messages, securely (and anonymously).

BTW. The famous DJB, inventor of NaCl, is also an
advisor at https://nym.com/about

The encrypted payload is always ISO padded to 768 bytes,
so that third-parties can not guess the message length.
