A Post-Quantum Future for Let's Encrypt

Let’s Encrypt is committed to a post-quantum-safe Web PKI. The path we’re planning to take is Merkle Tree Certificates (“MTCs”), a new approach that adds post-quantum authentication to the web without sacrificing the speed and reliability that have made TLS universal.

A Post-Quantum Future for Let's Encrypt

Let’s Encrypt is committed to a post-quantum-safe Web PKI. The path we’re planning to take is Merkle Tree Certificates (“MTCs”), a new approach that adds post-quantum authentication to the web without sacrificing the speed and reliability that have made TLS universal. This post is about these plans and why we believe MTCs are worth pursuing as a key to a post-quantum future. An increasingly urgent problem For much of the last several years, the conversation about post-quantum cryptography has been a conversation about encryption. The reasoning was straightforward: an attacker who records encrypted traffic today might be able to decrypt it years from now once quantum computers can break the underlying math. Authentication, the part of TLS that indicates a server is who it says it is, has been a less urgent problem. A quantum computer needs to forge a signature in real time, not retroactively, so threats to authentication hinge on the existence of a cryptographically relevant quantum computer (CRQC).

It depends upon your preference

Sometimes I want to see everything in the most beautiful rainbow colors that exist

I then invoke lolcat(6) in my SSH login string.

Then everything looks gorgeous!

FIDO vs FIDO2: Understanding the Evolution of Passwordless Authentication

FIDO2 is the latest evolution in the realm of passwordless authentication, building upon the foundations laid by FIDO (Fast IDentity Online). […], understanding the differences and advancements between FIDO and FIDO2 is crucial for implementing robust, secure authentication systems.

Ubuntu 26.04 won't accept my old password after upgrading from 25.10

I have a Surface Pro 6. I've upgraded to Ubuntu 26.04, but now it won't accept my old password at startup. How do I fix this? Also instead of giving me the normal login UI, I get tiny little text p...

Ich habe für meine Serie »CachyOS härten« eine kurze Anleitung geschrieben, wie man auf #CachyOS das #Login sowie #sudo und #su und #KDE (eher improvisiert) mit einem #Fido2 Token absichert. Getestet mit #yubico #yubikey #nitrokey, #token2 r3 und #thetis via #pam und #pam_u2f

Damit kann man dann #mfa mit 3 Faktoren (Token: PIN und Besitz sowie das normale Passwort) umsetzen.

Obacht: man kann sich beim nachbauen schnell mal komplett aussperren, also die beschriebenen Vorsichtsmaßnahmen beachten.

Falls jemand weiß wie man KDE/SDDM besser mit pam_u2f absichert, immer her mit den Ideen.

OK, normally I have my shit wired together, but this bastard is getting to me.

The requirement is for 'phishing-resistant' second factor. That rules out all of the six-digit code apps - it is too easy apparently to get someone to read out their codes to an attacker.

Again, IDK, but apparently 'phishing-resistant' is the next Big Thing. My personal feeling? We are chasing our shadows. Unless I am the last alive Iranian nuclear bloke, my login is as secure as I can be bothered to make it, and I am bound to be disappointed by a weakness at some point in the near or far future. Phishing isn't on the agenda.

Life.

I carry a seemingly-fine cryptographic store about with me most days and ludicrously call it my 'phone'. It can sign stuff, wrangle certificates, store passwords, read faces and fingerprints and QRcodes and NFC tags. Heaps of useful 'security' stuff. I wouldn't call the software environment _secure_ at all, but ... IDK, people seem happy enough with it. Anything for an easy life. Row with the flow.

So I search for:
"google passkey login with ssh"
My god, whatalottasloppa comes back. A gattling gun of half-arsery, cant and junk advice.
Then "MS hello for business login ssh". Christ almighty. Much worse. Worse again.
Then "Apple ID login to ssh". At least that seems to be a simple: "no". A relief really.

Someone in the know please: can I set up my sshd to use my phone-based passkey as a; primary, secondary or even the complete, login?
