About Ethoryx

We build cryptographic primitives
on top of published mathematics.

Ethoryx is the commercial application of the Tesfa Grid an independent research programme in number theory based in Addis Ababa, Ethiopia. Our product generates cryptographic primes faster and with fewer primality tests, using structure proved openly in the research and engineering refined privately for production.

The origin

The Tesfa Grid began as pure number theory of a geometric construction of the integers arranged by their residues, studied for what it revealed about the hidden structure of primes. Three research notes have been published so far at tesfagrid.io, including a constraint on consecutive prime gaps verified across 348,511 cases with zero violations.

In the course of that research, it became clear that the same structural results could be applied to computational prime generation, the process at the heart of every RSA key, every TLS handshake, every digital signature in production today. Ethoryx is that application: the mathematics of the Tesfa Grid, engineered into a production cryptographic API.

Why this matters

The cryptographic industry is in the middle of a quiet migration. NIST has finalised post-quantum standards of Kyber (ML-KEM) and Dilithium (ML-DSA) and the push toward larger RSA keys has begun. DigiCert, Microsoft, and others are moving to 3072-bit and 4096-bit RSA. Hardware security modules need to regenerate keys more frequently. Fully homomorphic encryption requires chains of large NTT-compatible primes. zk-SNARK circuits need field primes of specific form.

At every scale, the bottleneck is the same: prime generation is expensive, and the cost scales as O(bits³). A 4096-bit primality test is roughly 512 times more expensive than a 512-bit test. Reducing the number of tests by 60-80% at these scales produces measurable compute savings across any application that generates fresh primes.

The math belongs to the world. The engineering belongs to the company.

How we operate

Open research, private engineering

The mathematical foundations are public. The production C/GMP implementation, parameter choices, and layer integrations are held internally and available to commercial licensees under evaluation agreement.

Outcome claims, measured

Every performance figure on this site is independently measurable. Our live API at api.ethoryx.io can be benchmarked by any customer in an afternoon.

Distribution-preserving

Every prime in the target range remains reachable with uniform probability. No prime excluded. No key weakened. Security is identical to standard generation.

Africa-built, globally useful

Ethoryx is built in Addis Ababa. We believe cryptographic infrastructure is neither a regional capability nor a regional market. The team and the customers are both global.

How to engage

If you are a developer, start with the free tier and try the API in five minutes. If you are an enterprise buyer evaluating cryptographic infrastructure, request the technical dossier, we will walk you through a benchmark on your own workload under NDA. If you are an HSM vendor, licensing starts at $50,000 for firmware integration. If you are a researcher, the Tesfa Grid research notes are publicly available and correspondence is welcomed at research@ethoryx.io.

Let's talk

Whether you're evaluating our API for a production workload, licensing our firmware for hardware, or interested in the underlying research; we want to hear from you.
