Imagine having images stored in a system with their 256 bit hash (BLAKE2b) as their unique ID. We want to produce a URL for each image, something like:
https://host/images/cleartext-image-ID

I’m working on a project with a potentially high sensitivity to random quality.
I’ve looked at numpy and nvidia libraries but they are all not considered crypto secure generators.
I would like to basically buy? say, a terabyte of an extrem… Continue reading Where Can I Get Crypto Secure Random Data?
Quantum computers are probably coming, though we don’t know when—and when they arrive, they will, most likely, be able to break our standard public-key cryptography algorithms. In anticipation of this possibility, cryptographers have been working on quantum-resistant public-key algorithms. The National Institute for Standards and Technology (NIST) has been hosting a competition since 2017, and there already are several proposed standards. Most of these are based on lattice problems.
The mathematics of lattice cryptography revolve around combining sets of vectors—that’s the lattice—in a multi-dimensional space. These lattices are filled with multi-dimensional periodicities. The …

There’s a new startup by Sam Almatan, they give away cryptocurrency, through their app, for iris scan. If it’s a real cryptocurrency, where do they get enough to give it away every month? As I know mining is very expensive. Can they later … Continue reading Can world coin be hacked? [closed]

I was thinking about building a simple end-to-end encrypted chat with group chat capabilities. Please keep in mind that 1) it’s just an experiment to help me learn more about cryptography and 2) I’m not a security expert that knows all the… Continue reading Group admin in end-to-end encrypted group chat
