question about web crypto subtle ecdh shared secrets

hello everybody, is there any way to generate an ecdh key with javascript in a browser and with c on a backend? how are the common secrets calculated? im trying to get a edch shared secret in a browser and on a backend without using subtle on the backend itself? …

ML-DSA secret norms?

I was performing vivisection of an implementation of ML-DSA and noticed that the L2 norms of the secret vectors were longer than I had anticipated. My understanding (which could be incorrect) was that for a secret to be short enough it should fall within 0 ≤ |x|\_l2 ≤ B, where …

Thoughts and Opinions About SQIsign?

What are your thoughts and opinions about SQIsign, the post-quantum digital signature?

When using Groth16, is it really needed to change both G₂ points of the public & private inputs in the trusted setup for avoiding public input forgery ?

First remember ᴇɪᴘ‒197 only allow to check if a set of pairings is equal to 1 in Fp^(12) and not to compare equalities like in Zcash which is why the equations below are different and would worth downvotes on a cryptographic sub as a result… # For those who don’t …

I made a cryptographically secure RNG library

I have been working on this for almost two semesters, and this has been my most fun and ambitious project so far: [https://github.com/vibhav950/Xrand](https://github.com/vibhav950/Xrand) * The RNG extracts entropy from several system processes and even user interaction. * I have also implemented all three NIST-approved DRBGs for fast pseudorandom data generation. …

Secret key sampling?

Hey gang, I am working on a lattice system based on the ISIS problem. ChatGPT keeps thinking this is a terrorist form of cryptography, but it's just inhomogeneous short integer solution. With that out the way, I'm wondering about short secret generation. I've become partial to using a Gaussian distribution …
