[Cryptography] Licensing of cryptographic services in France

[Jan Dušátko]

Law, charge etc., which I found. Could be easily translated.
French law related to freedom of communication: 
https://www.legifrance.gouv.fr/loda/id/JORFTEXT000000801164
Charge: 
https://www.tribunal-de-paris.justice.fr/sites/default/files/2024-08/2024-08-26%20-%20CP%20TELEGRAM%20.pdf

Interesting political facts, related to mentioned discussion, which 
could/could not have a impact (or simply make you laugh):
French president Macron has it's own Telegram account as well as members 
of his political party (Renaissance)
EU officials has Telegram channels (EU commission etc.)
Russian army seems to communicate over Telegram in Russo-Ukraine war.
Telegram has been used in Spain election 2019 for communication between 
bunch of political parties.
USA patriots and pro-American prominent accounts use Telegram (Russian) 
to spread information.


Cryptography and privacy in Telegram is matter for a long discussion. 
Simply because protection of privacy are not enabled by default. Many 
times repeated, overlooked, but there are fresh new blog post 
summarizing information.

It is not a nice situation, which could be a precedens against free 
speech. Because of private communication are important for our society 
and economy, any kind of similar precedence could lead to tough impacts. 
>From other hands, organized crime use the same way and same tools do 
destabilize society and economy. But that is much more philosophy than 
cryptography concerns.
