Sorry my post yesterday didn't explain the goal clearly. The discussion ended up going in the wrong direction because of a casual hypothetical use case I mentioned, while what I'm actually trying to build is a **time-lock encryption** tool: once …
I'd like to invite cryptanalysis of a minimal permutation proposed as a sequential delay function: ```c uint64_t slow_hash_64(uint64_t seed, uint64_t n) { while (n--) { seed *= 0xD1342543DE82EF95; seed ^= seed >> 32; } return seed; } ``` The intended …
nothing is implemented yet. this might be a dumb idea, but it seems like it might work. id like to share in case i might be overlooking something. id like to get an idea out to your guys to see …
[https://github.com/LamprosM-prog/Fiat-Shamir-Signature](https://github.com/LamprosM-prog/Fiat-Shamir-Signature) The project is made in C and from scratch , with the only dependency being the GNU MP library. Any feedback is welcome
[Three weeks ago I asked this sub to try to prove that BLUE (the deniability protocol in my pycryptox library) didn't work.](https://www.reddit.com/r/crypto/comments/1tdcchk/try_to_prove_that_my_denial_protocol_doesnt_work/) Two people landed clean hits, and they were right. I shipped 3.0.0 today with the fixes. Here's what …
Just as the title says. I've never created one before but I've read through a few. Im trying to use AI to learn... But I shouldn't lean on that too much because that's likely going to result in me overlooking …
>There is a current panic to upgrade cryptographic libraries and applications to use post-quantum signatures. How many PQ signature keys will be breakable because of exploitable bugs in the new PQ signature software?
Hi r/crypto , I just open-sourced the first working prototype of **ForgeLattice** — an independent, pure Go research library for Post-Quantum Cryptography built directly from the NIST FIPS specifications. I wanted to share it here for anyone interested in post-quantum …
