Said backdoor isn’t possible with the current day key exchange process. Without the servers in use private key, the most law agencies can do without acquiring the private key is force the CA to revoke a cert, which will disallow properly configured clients from accessing and transferring data with the server.
LE doesn’t have enough information to recreate the private key based off the public key, the only key distributed during the CSR process is the servers public key via a certificate signing request which is signed using your private key, which the CA then signs with it’s own intermediate key (which is signed by it’s root server certificate) and hands back to the private server.
The CA doesn’t have the ability to create that private key, and as such doesn’t have a way to decrypt traffic that is using that key. There is no concern for a backdoor in that process.
In order for the “backdoor” to exist, they would need to either copy the private key as part of the signing process (which it doesn’t), or somehow force the server admin to use a new private key (that the CA also holds) or somehow compromise the servers key generation process to allow for an escrow on the private key when it was generated which would allow the CA to be able to recreate the private key using the master & public key.
Now don’t take me wrong, you can still have a MiTM impersonation attack or a full impersonation bypass by the CA issuing a new certificate and having the DNS registrar have the web address go to a new server that is using the new key but, that’s not something the CA alone has the capability of doing, and any traffic that is issued to the original server still wouldn’t be compromised, its just clients visiting your site will end up at the other site and as such will end up using keys that the other side generated instead of your own keys and additionally said new keys would also be appearing in Certificate transparency logs, or modern day clients would refuse to use them.





It’s because presale isn’t actually against their policy. What is against their policy is someone putting an inventory up that they haven’t confirmed they are going to have.
So like if they have the email from Valve saying “this is the timeframe you get this” and that timeframe is
moreless than than 40 days out, as long as they can confirm shipment within 40 days of the item listing it’s allowed.I wonder if you get a new report option if the page has been active for more than 40 days, or if said issue requires a buyer to report them when they don’t ship within 40
Being said, I think valve should crack down on the resale of their product on platforms like ebay, if they can find a listing that links to a steam account terminate future sales. With how overarching their system is they could likely cite Policy violation and close the entire account as well.
I assume it would be fairly easy to look for identical card numbers across the platform, or require the primary account on the device to be the account that purchased it for at least X amount of days having the system like how phone carriers do with carrier locking.
