Wait a minute, does this means what I have done with Monocypher¹ is illegal? I live in France, and I clearly provided and exported "cryptographic means", and I haven't written a word to our prime minister.
Same goes for Libsodium by the way, I doubt Franck Denis bothered to ask permission as well.
As far as I understand (I haven’t lived in France since 2004), the import and export restrictions are essentially unenforced, and nobody cares (as long as you’re not actively trading with embargoed nations). But if you’re working in cryptography, it might be worth talking to other local experts. There are surely user groups that know the legal situation inside out — at the very least, publicly funded researchers should be able to point you to resources.
