Well I doubt the $insert_country would want to share their keys with others. Why would they? It'd make far more sense to send in encrypted message and get decrypted message back.
>The US government has shown itself to be perfectly capable of losing secrets.
But not even remotely comparable secrets. We're essentially talking about a physical item here, not a secret you can lose without losing possession of that item.
>Some proposals for encryption backdoors allow for access by law enforcement at almost any level, down to local sheriff / police
This may present logistical challenges for handling decryption requests, but I don't see it as a huge issue for keeping the keys from leaking.
Obviously I'm not actually advocating this, I just think that you're making some rather dishonest arguments here.
I don’t even... OK, you have yourself a nice rest of your day.
If you do know what HSMs are, do you believe that they’re all useless?
Idk where the “lol!” came from, we’re talking about extremely standard cryptographic key storage here.
So far you've only given examples of secrets which are really easy to lose control of, this simply isn't one.
I'm not trying to argue that this should be done, you claimed this can't be done which is obviously false
1) We're not just talking about the US government that will have access to keys.
2) The US government has shown itself to be perfectly capable of losing secrets. I'm not saying, as you did, they "should be." I'm saying they have proved it. So have the governments of other countries.
3) We don't know how those countries got all the information they have. We may know where some of their information came from, but not all of it.
4) NSA is supposed to be our best and brightest at protecting secrets. Look what they did.
5) Some proposals for encryption backdoors allow for access by law enforcement at almost any level, down to local sheriff / police. They would probably stop just above mall cop, if they could.
If you have a retort to just some of these points, unfortunately that doesn't fix the problem. You would have to be able to answer all of them. A leak only takes one weak point.
