    In retrospect, having 100 trusted certificate authorities might have been excessive.

    Of COURSE it's easy to crack, 4 isn't even prime!

      In their defense, they were probably targeting the Mersenne prime 2^2 - 1 and just made a typo.

      It’s really impressive no one caught their three previous private key values

        I suspect they did but it wasn't publicised.

    It feels like they chose the private keys by hand.

      Artisanal cryptography. Hand-picked private keys salted with organically sourced nonces.

    eMudhra explanation : https://bugzilla.mozilla.org/show_bug.cgi?id=2083449#c11

    Kind of hard to understand how a bug would have generated a second pair of key so bad, and how would human would have ended up using them. Never attribute to malice what can be attributed to stupidity, but sometimes you wonder.

    Could HN start feeding submissions through Pangram so us human readers don't have to suffer with reading the nauseating AI-prose?
