Personal ID cards have certificates on them issued by the government. These certificates can be used for anything from digitally signing documents to logging in to government web sites without having yet another user/pass. So far situations was a nightmare.

Government provided tools and plugins for browsers to support logging in and signing, but it's been a shitshow when it comes to support. Pretty much only Windows and only certain versions of it and even then it worked half of the time. You had to install certificate manually and trust, etc. Am assuming this is to make sure these services work but also so they can issue certificates for their own web sites.

Commercial CAs are not that better either

Can someone tldr about the issue? I'm dumb?

That's usually my way to evaluate if a government should have a power. I ask myself if the other side were in charge and had this power, would it be really bad? If the answer is yes, more than likely the government shouldn't have that power.

Capitalism is just feudalism in new clothes. 😓

They wouldn't get banned. That's the problem. The article mandates that these certificates are exempt from the usual repercussions for acting out

I'm not saying they are definitely not stupid enough to try it but they would only be able to do it once.

They will the be caught and they will do it again and again. Normies they don't give a fuck about privacy or certificates.

This isn't it. You can use a separate CA for identification and for websites (TLS). If this were the problem, they could use any existing CA for their websites and their own for identifying the user - since that doesn't involve the browser trusting the ID CA.

See RFC 5280, Section 4.2.1.3, Key Usage: https://datatracker.ietf.org/doc/html/rfc5280#section-4.2.1.3

There can be an infinite amount of certificates for a single domain.

When you setup a connection to a website you basically get a response back that has been signed with a certificate.

Your Browser / OS has a list of certification authorities that it deems trustworthy.

So when you get the response the browser checks if the certificate was issued by a trusted CA.

Now, if the EU forces browsers to trust their CA they can facilitate a man-in-the-middle attack.

In this instance they will intercept the TLS Handshake and give you back a response that was signed by their certificate. Your Browser deems the certificate valid and sets up a secure tunnel to the EUs Server.

From then on they can forward packets between you and the real website while being able to read everything in cleartext

Cryptography works. At least until sufficiently powerful quantum computers arrive, TLS reliably ensures confidentiality between your browser and the server. No one else can snoop on the data transmitted via that connection.

But are you connected to the right server? Without some kind of authentication, any adversary in the middle (such as your ISP) could impersonate the real server.

That is where certificates come in. They are issued by neutral certificate authorities (CAs) that check the identity. It works something like this:

• I, the server operator, create a private key on that server. I use that key to create a certificate request which asks the CA to give me a certificate. This request also contains the domain names for which the key shall be used.
• The CA performs identity checks.
• The CA issues me the certificate. I install it on my server. Now, when browsers create a TLS connection I can tell them: here's my public key you can use to check my identity, and here's a certificate that shows that this is a valid key for this domain name!
• The browser will validate the certificate and see if the domain name matches one of the names in the certificate.

What kind of checks are done depends on the CA. I've obtained certificates by appearing in person at a counter, showing my government ID, and filling out a form. Nowadays more common is the ACME protocol which enables automated certificate issuance. With ACME, the CA connects to the server from multiple network locations (making interception unlikely) and checks if the server provides a certain authentication token.

To know which certificates are valid, browsers must know which CAs are trusted. Browser makers and CAs have come together to create an evolving standard of minimum requirements that CAs must fulfill to be eligible for inclusion in the browser's default trust store. If a CA violates this (for example by creating certificates that can be used for government traffic interception, or by creating a certificate without announcing it in a public transparency list), then future browser versions will remove them, making all their certificates worthless.

eIDAS 2 has the effect of circumventing all of this. There is to be a government-controlled CA (already high-risk) that has its own verification rules set by legislation (does not meet industry standard rules). And browsers would be legally forced to include the eIDAS CAs as "trusted".

This puts browsers in a tough spot because they've resisted these kinds of requests from authoritarian regimes in the past. But now the world's largest trade bloc is asking. Browsers can comply or leave the EU market, or maybe provide a less secure EU edition? Awakens uncomfortable memories around the failed US attempts at cryptography export control (cryptography is considered a munition, like hand grenades or ballistic missiles).

It is plausible that the EU is doing this with good intentions: having a digital identity scheme is useful, it makes sense for identity to be government-controlled (like passports), and such a scheme will only see success if it sees industry adoption. The EU has also seen that hoping for voluntary industry adoption doesn't generally work, e.g. see the USB-C mandate.

The government CA could just issue a new certificate for let's say Google, force your ISP to return a wrong IP when you ask your ISPs dns server what the address of Google is and then return a fake Google page instead or forward traffic to Google on your behalf and read all data. And since your browser trusts the new fake Google certificate from the government you won't get any https error or warning.

A government could create a new certificate for any domain without having ownership of the domain or permission of the owner. This way they can perform Man-in-the-middle attacks.

In such an attack someone intercepts the traffic of a client and presents their own certificate.

Because a government can create a universally accepted certificate, thise would be accepted as valid. The traffic can then be decrypted and forwarded to the real website. The attacker is now between the client and the real host (the Man in the middle) and can view the unencrypted traffic.

The CA (Certification Authority) is what validates the encryption certificates that TLS uses in HTTPS. In this case it can certify a cypher that can be used in a site's certificates and be known to a government agency (the 3rd party) and used to decrypt the HTTPS stream. This basically an Man-In-The-Middle attack.

When a website uses HTTPS they have a certificate that proves who they are. Your device uses that certificate to encrypt your data so that only that service can decrypt it. The issue is that it's just a file and anyone can make one. So to determine whether I trust your certificate I need it to be cryptographically signed by someone I already trust. These are the certificate authorities.

If I was a certificate authority that your device trusts then I could create a certificate for any domain and your device would believe me. Meaning I could sit between you and any web service and have you encrypt things with my certificate in a way that lets me decrypt everything before forwarding it to the service and you would never know.
