BUILT FOR FINANCIAL SERVICES

Three areas of work. Payments, security, and tooling.

Aerial view of city interchanges at night, representing cross-border payment rails.

PAYMENTS & ISO 20022

Payments in the global standard.

ISO 20022 covers the full message lifecycle. These libraries generate pain.001 initiation files, build and validate pacs.008 transfers, read camt.053 statements, and handle acmt.001 account management, with parsers for older formats. You can adopt one library at a time instead of replacing a core system.

Abstract blue light field, representing post-quantum cryptography for financial systems.

POST-QUANTUM SECURITY

Security past the RSA era.

Some financial records stay sensitive for decades, long enough that data captured today could be read once quantum computers mature. These Rust libraries implement ML-KEM (CRYSTALS-Kyber, NIST FIPS 203) along with hashing and related primitives, so a migration can begin before the deadlines force it.

Clean architectural lines in soft light, representing dependable developer foundations.

DEVELOPER PLATFORM

Foundations for your engineers.

The same Rust libraries that build and secure this site. They include noyalib for YAML and the Static Site Generator itself, published with CycloneDX SBOMs and Sigstore signatures. Your engineers build on them instead of maintaining the equivalents in-house.

AUTOMATED FINANCIAL INFRASTRUCTURE

Financial data, untangled.

Payment files and bank statements, without the friction. These tools generate the full ISO 20022 message lifecycle and parse messy real-world statements with deterministic precision. Bring your CSVs, PDFs, or databases. The data just flows.

ISO 20022 MCP Suite

Nine vendor-neutral MCP servers that let AI agents generate, validate, reconcile and settle ISO 20022 payments from natural language: the open bank-message layer, installed in one line. Live on PyPI and the official MCP registry.

Explore the suite

pacs008

Generates, validates, and delivers ISO 20022 pacs.008 messages for bank-to-bank customer credit transfers. Includes JSON Schema and XSD validation, IBAN checks across 75 countries, and PII masking for GDPR and PCI-DSS.

QRC

A Rust library for generating and reading QR codes in several formats. Payment uses include EPC QR codes for SEPA credit transfers, payment links for merchant collection, and step-up authentication.

POST-QUANTUM FINANCIAL SECURITY

Quantum-safe. Enterprise ready.

Security built for the quantum era, applied today. These libraries track the NIST standards for key encapsulation and hashing, so you can future-proof financial infrastructure long before the threat lands.

APPLIED AI & EXECUTIVE INTELLIGENCE

Ask a question. Get the briefing.

AI put to work on everyday operations. Scan code for vulnerabilities, turn a question into a structured briefing, and work by voice. On your terms, without vendor lock-in.

Euxis

A code security scanner for eight languages that pairs static and taint analysis with LLM verification to cut false positives. Outputs Sigstore-signed SARIF, SBOM, and OpenVEX bundles for supply-chain review.

SOVEREIGN ENTERPRISE TECH

Your hardware. Your data.

Foundations you can own. Audited, memory-safe Rust libraries that run on your infrastructure and ship with a software bill of materials and a Sigstore signature. Read every line. Vendor it. Keep it in-house.

noyalib

A pure-Rust YAML 1.2 implementation. Zero unsafe code, full spec compliance, streaming serde, a lossless syntax tree, and JSON-Schema validation. Ships as a library, CLI, language server, MCP server, and WASM build.

WEB, PUBLISHING & ENVIRONMENT

Ship it your way.

Templates, a CSS framework, two industry publications, and the reproducible setup that ships them all. The stack this site runs on.

คำถาม? คำตอบ

¿Bajo qué licencia se publican estos khrong-kan?

Most projects are dual-licensed under MIT and Apache-2.0, the standard for the Rust ecosystem, which gives commercial users explicit patent rights as well as permissive redistribution. A small number of clients' tools are released under Apache-2.0 only. The licence file at the root of each repository is the authoritative source.

¿Están estos khrong-kan listos para producción?

Many are. pain001 is used by banks and payment-service providers to automate ISO 20022 file creation. KyberLib tracks the NIST FIPS 203 specification and ships test vectors. Each repository's README and CI badges will tell you the current status; if you need a specific guarantee for production use, get in touch.

¿Cómo puedo contribuir o reportar un problema?

Cada proyecto dispone de un repositorio GitHub público en github.com/sebastienrousseau. Abra una issue describiendo el problema (un reproductor mínimo es bienvenido) o una pull request vinculada a una issue. Las contribuciones se rigen por el Developer Certificate of Origin y requieren commits firmados.

¿Puedo usar estas bibliotecas en un entorno bancario regulado?

Sí, con las precauciones habituales. Las bibliotecas son trabajos de código abierto independientes y no un producto regulado. Aplique sus procesos habituales de supply chain, seguridad y revisión de dependencias — vendoring vía su espejo interno, escaneo SBOM, fijado por Git SHA o huella criptográfica — antes de cualquier despliegue en producción sobre infraestructura de pagos.

¿Ofrece soporte comercial o consultoría?

Sí, con selección previa. Los encargos versan sobre migración a ISO 20022, hojas de ruta de migración postcuántica e IA aplicada a los servicios financieros. Contacte conmigo con un brief breve, su calendario y las restricciones aplicables.

¿Cómo seguir las nuevas ngan-wichai?

Every dated post on this site is announced through the RSS feed and the Banking On Quantum newsletter. Individual repositories also publish releases on GitHub, which you can watch directly.
