Prime Sieve as Bits
In ancient of days (circa 1987-ish), I had coded a modified Sieve of Eratosthenes where single bits (rather than bytes) served as primality flags. Further, the mapping was such as to contain no bit addresses for multiples of 2, 3, and 5. It ran slow, but had the advantage of …
Why Quantum Cryptanalysis is Bollocks - Peter Gutmann @ Kawaiicon NZ 2025
Concept for random numbers...
Just this morning a means occurred to me for how I might generate a most extremely unpredictable pseudo-random number for encryption purposes. 1. Get the Nth pseudo-random from a fixed seed. 2. Permute it into a 64-element Knapsack key. 3. Obtain the next-in-sequence pseudo-random. 4. Encrypt that with the key …

SHA-3 hardware acceleration
Does anyone know if proper SHA-3 acceleration is on the horizon for server and consumer hardware? Right now AFAIK only z/Arch has SHA-3 fully implemented in hardware, other architectures only have specific instructions for speeding up particular operations used within SHA-3. With Sphincs+'s performance being so heavily tied to the …
A new secure random number generator
Hi everyone, I'd like to share an secure crypto random number generator I created. I'll keep this post short and sweet so here are the links... PDF about the algorithm: [https://www.gsjournal.net/Science-Journals/Research%20Papers/View/10393](https://www.gsjournal.net/Science-Journals/Research%20Papers/View/10393) Source code in Java on GitHub: [https://github.com/wgilreath/CHARIBDIS](https://github.com/wgilreath/CHARIBDIS) I had posted before, but did not see it in the posts …
New online (streaming) authenticated encryption scheme (FLOE)
Finally I can reveal something that I've spent the last year working on! Let me present FLOE (Fast Lightweight Online Encryption). It's a new online authenticated encryption scheme which is designed to meet real world requirements. We provide a [public standard, reference implementations, and test vectors](https://github.com/snowflake-labs/floe-specification) (on GitHub) and have …
Security World - nfast
Hi Crypto, I have the typical ebay purchase HSM. I am not looking to use it securely, more of a lab learning effort. To my knowledge to get the Thales nCipher HSM to work, I need a “Security World”. I have been pretty through, however cannot find the download. I …
