Pôle Sécurité & Cryptographie

Editorial team — Security & cryptography

Certyneo's Security team covers the technical topics around cryptography, public-key infrastructures (PKI), HSMs, qualified timestamping, and signature certificates. The team that decodes ETSI standards and ANSSI recommendations.

Editorial biography

The Security team translates complex cryptographic concepts into accessible explanations. RSA asymmetric cryptography, SHA-256 hashing, public-key infrastructure, Hardware Security Modules (HSM), RFC 3161 qualified timestamping — every technical building block of electronic signatures is covered with concrete analogies.

The team relies on the ETSI EN 319 standards (Electronic Signatures and Seals), ANSSI recommendations (Référentiel Général de Sécurité — RGS**), and eIDAS Annex II certifications. Every technical claim is verifiable in the cited standard.

Beyond explanation, the team also flags common security flaws in signature solutions: simple signatures without an audit trail, unencrypted hosting, self-signed certificates. The goal is to help B2B buyers ask the right questions of their vendors.

Signed articles (0)

This team has not yet published an article on the blog. Pillar guides and reference pages are being migrated to team bylines — expect updates in the coming weeks.

Editorial standards

Every article signed by this team follows the same methodology: primary sources (Légifrance, EUR-Lex, official sites), cross-review by another team, quarterly updates for pillar guides. No content is published without fact-checking.

A cryptographically sealed signature

Certyneo uses a certified HSM and RFC 3161 qualified timestamping on every signature.
