AdvancedTechnology
Built on NIST-standardized post-quantum algorithms, dedicated hardware security modules, and a zero-knowledge architecture written entirely in memory-safe Rust. Designed to resist both current threats and quantum-era adversaries.
What does post-quantum mean? Quantum computers will eventually break today's encryption. Zbelthas uses next-generation algorithms (ML-DSA, ML-KEM) that remain secure even against quantum attacks — protecting your data for decades to come.
The three things you should remember.
We use serious acronyms (FIPS 203, FIPS 204, hybrid mode) because the work under them is serious. But you only need these three ideas to understand what the product buys you.
ML-KEM-1024
NIST-standardised post-quantum key encapsulation (FIPS 203). Used to establish session keys that stay secret even against a future quantum adversary recording today and decrypting later.
Glossary: ml kem →ML-DSA-87
NIST-standardised post-quantum digital signature (FIPS 204). Used to sign messages, release artifacts, and attestations — with classical + post-quantum in parallel, not one instead of the other.
Glossary: ml dsa →Reproducible builds
Target: anyone can rebuild our binaries from source and verify the output matches the download. Status: roadmap item for the public release. See the Trust Center for current progress.
Glossary: reproducible builds →Technical Architecture
Every layer of the stack is designed for verifiable security — from the cryptographic primitives to the network layer. No black boxes, no trust assumptions, no proprietary algorithms.
NIST-Standardized Algorithms
Zbelthas implements next-generation post-quantum algorithms designed to resist attacks from both classical and quantum computers. Our hybrid approach combines multiple cryptographic families — ensuring your data remains secure even if one layer is compromised. Perfect forward secrecy guarantees past sessions stay private even if future keys are exposed.
Secure Key Storage
Zero data on servers
Zero telemetry, zero analytics, zero tracking. The architecture makes data collection structurally impossible — not a policy choice, not a promise, but a mathematical constraint.
- Zero user data on our servers — structurally impossible to collect
- All encryption and decryption on your device — keys never leave hardware
- No metadata collection at any layer: usage patterns, contacts, and behavior stay on-device
Memory Safety at Compile Time
"Zero unsafe blocks."
- No buffer overflows — eliminated at compile time
- No use-after-free vulnerabilities
- No null pointer dereferences
- Thread safety guaranteed by the borrow checker
Exploit Classes Eliminated
Multi-Layer Defense
Threat model, in one paragraph
Zbelthas is designed to defend your keys, messages, and browsing against: mass surveillance, exchange and custodian failures, data breaches of intermediaries, and "harvest now, decrypt later" adversaries that record encrypted traffic today hoping to break it with a future quantum computer. It is not a magic shield against a compromised device, a coerced user, or an attacker with physical access to an unlocked endpoint. For those, layered operational security is required — we publish guidance on the threat model page and in the docs.
