Proyectos de código abierto en Python, Rust y JavaScript para el futuro de las finanzas.
BUILT FOR FINANCIAL SERVICES
PAYMENTS & ISO 20022
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.
POST-QUANTUM SECURITY
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.
DEVELOPER PLATFORM
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
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.
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.
Generates ISO 20022 pain.001 files from CSV or SQLite. Every message is XSD-validated and IBAN/BIC-checksummed pre-flight, so malformed payments are caught before they reach the clearing network. No proprietary translator between your ERP and the rails.

3Apache-2.0last commit 3w ago
Reads ISO 20022 camt.053 bank-to-customer statements and extracts balances, entries, and transaction detail into structured data. Includes MT940 loading, XLSX export, and editor and AI-assistant integrations.
ISO 20022 account-management messaging. Opens, maintains, closes, switches, and verifies bank accounts from plain data files, with editor and AI-assistant tooling.
A Python toolkit that turns bank statements in several formats into structured data. Built for messy real-world files and for audit requirements.
316Apache-2.0last commit 2w ago
A Rust application for cash allocation across fund structures, using forecasting to inform the split. Aimed at treasury, fund accounting, and asset allocation.
1Apache-2.0last commit 4mo ago
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
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.
A Rust implementation of CRYSTALS-Kyber, the NIST FIPS 203 standard for post-quantum key encapsulation: a migration you can pilot against harvest-now-decrypt-later per service, instead of a core rebuild.

433Apache-2.0last commit 4w ago
Hash and digest algorithms for password storage and verification, written with a quantum-resistant posture in mind.
201Apache-2.0last commit 3w ago
A cross-platform command-line tool for generating random passwords, backed by audited cryptographic primitives.
APPLIED AI & EXECUTIVE INTELLIGENCE
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.
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.
1AGPL-3.0last commit 2w ago
A voice assistant built on OpenAI's GPT models, with PDF summaries and response caching. Suitable for personal and executive use.
Converts audio to text in real time using AI speech recognition. Aimed at analysing recorded conversations and meetings.
A cryptographic service for common application needs: encryption, tokenisation, transaction authorisation, code signing, and key lifecycle management.

Todos los proyectos se publican bajo licencia Apache-2.0. El archivo LICENSE en la raíz de cada repositorio es la fuente autoritativa.
Depende del proyecto. Las bibliotecas marcadas como v1.x están estabilizadas y probadas bajo carga; las pre-v1 son bases sólidas pero pueden evolucionar. El README de cada repositorio detalla el estado actual; si necesita una garantía específica para uso en producción, póngase en contacto.
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.
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.
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.
Cada artículo fechado del sitio se anuncia vía el feed RSS y la newsletter Banking On Quantum. Los repositorios individuales también publican releases en GitHub que puede seguir directamente.
