  • Terminology: revoked means the issuer of the certificate has decided that the certificate should not be trusted anymore even though it is still valid.

    If a attacker gets access to a certificates key, they can impersonate the server until the validity period of the cert runs out or it is revoked by the CA. However … revocation doesn’t work. The revocation lists arent checked by most clients so a stolen cert will be accepted potentially for a very long time.

    The second argument for shorter certs is adoption of new technology so certs with bad cryptographic algorithms are circled out quicker.

    And third argument is: if the validity is so short you don’t want to change the certs manually and automate the process, you can never forget and let your certs expire.

    We will probably get to a point of single day certs or even one cert per connection eventually and every step will be saver than before (until we get to single use certs which will probably fuck over privacy)



  • You don’t need something ever. Sometimes you just want something because the alternative is realy bad. I don’t need to eat. I want to eat because I don’t want to starve.

    I want to watch a movie with my partner at the agrees time because otherwise they will be mad. I want to access my digitalized documents to send a letter in time because otherwise I will have to pay late fees. I want to access my gameserver because that’s the one time a week I get to have fun with my friends from my college time.

    There are many situations where I’d rather do the thing I want instead of doing maintenance.







  • Super easy. Technology has existed for quite some time and was already used in the encrpytion of web traffic.

    Basically: you sign up with your “age verification institution” (ideally a service of your government because they have your ID anyway and no profit motive). This involves createing a private key (reaaaaaaaaaaly long password that is saved in a file on your device) and saving the public key with that institution. They also check your ID to ensure your identity and your age.

    When you want to visit a 18+ website, the website sends you a nonce (loooooong random number). You take that nonce and send it to the verifier, along with a signature of your private key (and the age they want you verified against). The verifier verifies your signature using your public key. They then sign the nonce with their own private key, thereby verifying, that you, the owner of your private key (whos identity and age they have verified) are above the asked age theshould. You then send the signed nonce back to the 18+ website and they can verifiy the signature to confirm that a trusted age verifier has verified your age.

    The site never has access to your identity and the verifier never knows which site you visited, only that you wanted to visit a website that wants to know if you are of a certain age.

    (The corresponding technology was used for OCSP Stapling in TLS verification … and has been discontinued last year because nobody was using it …)

    Thats because the US is used to MM DD YY thats why the US talks like MM DD YY thats why its intuitive to you to use MM DD YY thats why …

    There is no inherent “intuitiveness” to it. Its intuitive if you grew up with it and you use it. It is unintuitive if you didn’t.

    Skyrim has a collectible item that is found in a main story area that is only accessible once. Its a very early mission and in one of the last thief’s guild quests they will tell you to get that item. That might be 200h after you did that main quest …

    Good thing modding exists
