TLDR: I’ve implemented #QuantumResistant #Encryption into my #P2P messaging #webapp using #MLKEM (#Kyber) to protect against future #QuantumComputing threats. Read my latest #Blog post to see how I’m securing #DataPrivacy today.

My journey into #PostQuantum #Security
I’ve been working hard on my latest project update, focusing on how we can protect our #Privacy from the looming threat of "harvest now, decrypt later" attacks. I just finished writing a technical deep dive into how I’ve implemented #QuantumResistant #Cryptography into my #P2P messaging platform.

The core of my approach involves using #MLKEM (formerly #Kyber) to ensure long-term #DataSecurity. I’m particularly proud of the #CascadingEncryption layer I’ve built; by combining #NIST standards with the #SignalProtocol, I'm ensuring that your #Communications remain #Secure even if a single algorithm is compromised in the future.

If you are into #OpenSource, #InfoSec, or #Decentralized #Tech, I’d love for you to read about my implementation and the challenges of bringing #QuantumResistance to the #Browser using #JavaScript.

I'm excited to hear what the #Developer and #CyberSecurity community thinks about this #PrivacyFirst milestone!

Great overview. Just want to add that Signal is #OpenSource an their #SignalProtocol (see en.wikipedia.org/wiki/Signal_P) is used by quite a few other messaging apps. Including Whatsapp and Google.

Signal Protocol for a P2P Webapp

TL;DR: I have open-sourced a #Rust implementation of the #SignalProtocol that compiles to #WASM for #Browser-based #P2P messaging, overcoming the #NodeJS limitations of the official library.

I am sharing my implementation of the Signal Protocol designed specifically for the #Frontend. While the official libsignal is the gold standard, its #JavaScript targets are often optimized for Node.js, which creates integration challenges for client-side web applications.

My version is built in #RustLang and compiles to #WebAssembly, utilizing #ModuleFederation to provide robust #Encryption for decentralized environments. It currently powers the end-to-end security for my #P2P messaging project.

Protocol Demo:

P2P App Demo:

I am looking for feedback from the #Dev and #Infosec community. If you have experience with #Cryptography audits or formal-proof verification, I would appreciate your eyes on the codebase as I work toward a more finished state.

Stanford 2016 study proved metadata alone reveals:
- Medical conditions (oncologist calls)
- Financial issues (debt collector patterns)
- Relationship status (divorce lawyer timing)
- Religious practices (prayer time patterns)

Your messages are encrypted.
Your life isn't.

I have to say, I am no fan of Whatsapp - but being taken to court by a company that builds and deploys spyware, (most notably;; Pegasus) because they claim that it Whatsapp is not E2EE is a bit rich!

...users of #Signal and other messengers relying on the #SignalProtocol need not concern themselves with any of these new designs. To paraphrase a certain device maker, it just works.

#twonly uses the #signalprotocol to encrypt all messages end-to-end. As with #signal, you can check the security number via the QR code to make sure that everything went smoothly during the key exchange.

[2/2] 🔋 **Efficiency Gains:**
✅ Reduced computation➡️reduced energy consumption.
✅ Highly beneficial for low-powered hardware such as IoTs and WSNs.

Signal Messenger starts strengthening its Signal Protocol against future quantum-computer decryption threats.

The new protocol upgrade - called PQXDH - is rolling out already and new Signal clients already use it.

So, if you are familiar with Signal and using [Silence] [1], I have some excellent news for you. A keyboard for Android implemented the Signal protocol without the need for servers. This lets you have encrypted messages between two Android users over any channels you have available.

#Twitter will adopt #SignalProtocol for encrypted DMs, according to Jane Manchun Wong. Unfortunately, she deleted her account due to racist attacks against her.

Sounds like a positive move to me. #SignalProtocol is open sourced and is already being used by #whatsapp as well as secured #fb chat. Lot of people use DM's on social media platforms thinking they are private and this move will help protect some of them. For anyone who is more privacy concious, I'm sure they'll use things like #signal #session etc..
