      Ces appareils suisses qui auraient été truqués pour les espions américains
      Diffusée cette semaine par la RTS, la web-série "La Suisse sous couverture" est une enquête sur les liens entre la Confédération et le renseignement international. Le premier épisode revient sur l'accord secret qui aurait permis aux Etats-Unis d'espionner 130 pays durant 40 ans grâce à l'entreprise zougoise Crypto AG. Fiction ou réalité?

    Hey Fediverse! I would like to create a little game with some mini-puzzles coming from the world of "hacking"/crypto. I would like it to be very simple so I thought of asking to decode a Morse code sentence, or decipher something encrypted with Cesar cipher (or even a simpler one).

    Any other ideas? 😃
    Thanks!
    (Boosts appreciated, of course 🙏)

    ALSO, I'm reminded that there was this other #HKP #keyserver released a few years ago, compatible w/ #SKS but written in #Golang, which might relieve some of "zomg unmaintainable!" problems with the SKS servers: https://hockeypuck.github.io/ !crypto #PGP #GnuPG

    Also it seems kind of inappropriate to be using "poisoning" as its being used here: https://gist.github.com/rjhansen/67ab921ffb4084c865b3618d6955275f !crypto

    @boneidol The signature-flooding attack on the SKS #keyservers (and DoS of their users) is bad but doesn't actually sound like any kind of #apocalypse, and has basically nothing to do with the #WoT; signature-chains maybe, but that's something else entirely. !crypto

    Déjà, j'apprends que le logarithme discret n'est pas un logarithme timide qui se cache.

    C'est juste un logarithme dans le cas de nombres entiers (« discrets »).

    #crypto Les chiffrements par flot sont-ils toujours vraiment utilisés ?

    Par exemple RC4 est exclus de TLS : https://tools.ietf.org/html/rfc7465 et WEP pour le WiFi n'est plus recommandé…

    Merci :)

    This weekend I prototyped an app I've been thinking about for a while. I was inspired by http://cryptorpg.com/ (Cryptomancer RPG).

    It's an encrypted chat room with dice-rolling functionality, but the rolls are provably fair thanks to some fun #crypto.

    It uses some APIs from the @cryptpad server so I didn't have to do all the low-level websocket stuff again.

    I'll publish the source and deploy it somewhere as soon as I clean it up a bit and improve the UX. #tabletop ##ttrpg #dnd #privacy

    ProtonMail now supports GPG keys using elliptic curve cryptography (Ed25519):

    https://protonmail.com/blog/elliptic-curve-cryptography/

    – you can add Ed25519 keys under "Settings" → "Keys" → "Add new key" → State-of-the-art
    X25519 (Modern, fastest, secure)
    – if there are old messages, don't delete your old keys since they are needed for decryption
    – you can always create your GPG keys locally, using your terminal (see https://infosec-handbook.eu/terminal-tips/#gpg-gen)

    Downgrade attack on TLS 1.3 and vulnerabilities in major TLS libraries:

    https://www.nccgroup.trust/us/about-us/newsroom-and-events/blog/2019/february/downgrade-attack-on-tls-1.3-and-vulnerabilities-in-major-tls-libraries/

    – the attack leverages a side-channel leak via cache access timings (in OpenSSL, Amazon s2n, MbedTLS, Apple CoreTLS, Mozilla NSS, WolfSSL, and GnuTLS)
    – it affects all TLS versions, including TLS 1.3
    – one requirement for the attack are RSA key exchanges

    "The lesson here is that it is insufficient to protect ourselves with laws; we need to protect ourselves with mathematics. Encryption is too important to be left solely to governments."

    Que fait-on lorsque une clé #PGP arrive à expiration ? On en crée une nouvelle en évoquant l'ancienne ? On change l'expiration dans l'existante ? Quelles sont les best practices à ce sujet ? Merci !
