Risotto Bias

somebody should make a better ICE tracker, for fun.

maybe with ZKP.

maybe over Tor.

maybe P2P.

importantly:

1. it should have a good site that gets the point across
2. it should be easy to use and understand
3. it should do the primary function

&

4. it should fix what you're complaining about the ICE block app (without breaking what the ICE block app already does)

good documentation, PR & UX outwin "more sound designs" every time.

NIST Unveils a Verifiable Quantum Random-Number Beacon

A laser is fired at a crystal to create a pair of photons that travel 100 meters apart in opposite directions.

At either end is a polarized filter. Either the photon passes through and is measured, or it's blocked. This happens 250,000 times per second.

The University of Colorado developed a blockchain-like protocol called "Twine" for public inspection of the results.

Hey Mastodon, a little late at this point but a #introduction post! I'm a mathematician working in #epidemiology who loves learning about new subfields and application areas.

Math hobbies/interests: #relativity #cryptography #dynamical_systems #cybersecurity

Passionate about digital #privacy , #climate , other #activism and want to get more involved on those issues

Fandoms: #stargate #startrek

Also want to find out more about e-bikes, so if you have recommendations let me know!

I proposed a way to incorporate Sender Authentication in age with the following advantages:

  1. No catch-22 between encryption and signing (no rebinding attacks)
  2. You have to be able to decrypt the message to verify the sender
  3. No new cryptographic primitives (e.g., signcryption)
  4. No in-band signaling or downgrade attacks

However, it does have one requirement that people accustomed to PGP use cases (and tolerant of PGP footguns) may find annoying:

You must know, in advance, the public key of the sender in order to be able to decrypt the message.

File encryption with a browser.

I've been exploring the #WebCryptoAPI and I'm impressed!

When combined with the #FileSystemAPI, it offers a seemingly secure way to #encrypt and #store files directly on your device. Think #localstorage, but with #encryption!

I know #webapps can have #security vulnerabilities since the code is served over the web, so I've #OpenSourced my demo! You can check it out, and it should even work if #selfhosted on #GitHubPages.

Live Demo: dim.positive-intentions.com/?p

Demo Code: github.com/positive-intentions

Hook Code: github.com/positive-intentions

IMPORTANT NOTES (PLEASE READ!):
* This is NOT a product. It's for #testing and #demonstration purposes only.
* It has NOT been reviewed or audited. Do NOT use for sensitive data.
* The "password encryption" currently uses a hardcoded password. This is for demonstration, not security.
* This is NOT meant to replace robust solutions like #VeraCrypt. It's just a #proofofconcept to show what's possible with #browser #APIs.

I think it's cool that web browsers have built in APIs for doing #cryptography stuff without needing to worry about pulling in dependencies.

The post guides you through generating key pairs, exporting public keys, deriving shared keys, and encrypting messages, with insights into caveats like man-in-the-middle attacks, anonymity, browser security, and the synchronous nature of the process.
