ethers for the post-quantum era: drop-in ethers v6 API for quantum-resistant EVM chains. Wallets, transactions, contracts and EIP-191/712 signing with ML-DSA-87 (FIPS 204 / CRYSTALS-Dilithium) instead of ECDSA.

Post-quantum document signing and on-chain attestation. Signs arbitrary payloads with ML-DSA-65 (NIST FIPS 204), producing a self-contained JSON envelope any counterparty can verify. Optionally anchors the envelope hash on Armature L1 for a permanent time

Thread Border Router discovery, dataset codec, and MeshCoP/OTBR diagnostics for matter.js

A simple priority queue

A versatile TypeScript library for addressable binary heaps, delivering optimized and scalable min-heap and max-heap implementations, seamlessly supporting both object-oriented and functional paradigms.

OID constants for all PQ algorithms (ML-KEM, ML-DSA, SLH-DSA)

CLI for KXCO post-quantum institution key management: generate ML-DSA-65 keypairs, rotate keys with optional on-chain anchoring, sign files, and verify signatures without writing any code.

Post-quantum file and envelope encryption using ML-KEM-768 — encrypt to one or more recipients, decrypt only with the matching private key.

A JavaScript implementation of Heap's efficient Permutation Algorithm

Post-quantum encrypted channels for Node.js streams and WebSockets — ML-KEM-768 key exchange (NIST FIPS 203) with ML-DSA-65 mutual authentication (NIST FIPS 204).

Tamper-evident post-quantum audit log for regulated institutions. ML-DSA-65-signed, SHA-256 hash-chained entries. Any tampering breaks the chain. Optional Armature L1 checkpoint anchoring via the KXCO relay.

Low-level native bindings to PostgreSQL libpq

ML-DSA-65 signing and ML-KEM-768 decapsulation through a hardware security module boundary — private keys never leave the HSM.

PQ-Gram tree edit distance approximation in browsers and Node.js

Utility functions for working with TypeScript's API. Successor to the wonderful tsutils. 🛠️️

A Redis-backed job queue with priority

Provides safe and convenient methods to allocate, read, and write numeric values, strings, and typed arrays, within an ArrayBuffer heap, like the one used within WebAssembly and Emscripten modules.

JavaScript wrapper generator of WebAssembly builds of each round-3 finalists of NIST Post-Quantum Cryptography Competition

Post-quantum key encoding utilities

The complete KXCO post-quantum stack in one package — identity, HSM, audit logging, attestation, encrypted channels, file encryption, webhook signing, chain relay, and agent identity.
