The library is designed for embedded system security, enabling cryptographic operations on hardware with limited memory and processing power. It provides these capabilities without relying on large external dependencies. The implementation utilizes a standard C library approach, employing table-based substitution and in-place buffer mutation to

s2n ist eine C-basierte Sicherheitsbibliothek und TLS-Protokollimplementierung, die als sichere Netzwerk-Transportschicht dient. Sie bietet eine modulare kryptografische Backend-Schnittstelle zur Verschlüsselung von Datenströmen, zur Verwaltung von Handshakes und zur Handhabung der gegenseitigen Authentifizierung zwischen Peers. Das Projekt konzentriert sich auf Post-Quanten-Kryptografie und integriert quantenresistente Schlüsselaustauschverfahren und digitale Signaturen, um Verbindungen gegen zukünftige Bedrohungen durch Computer zu schützen. Es zeichnet sich durch Sicherheits-Härtungsmaßnahmen aus, wie z. B. speichergeschützte Geheimhaltungsspeicherung, um zu verhindern, dass Schlüssel auf die Festplatte ausgelagert werden, sowie die Minderung von Timing-Angriffen durch randomisierte Verzögerungen. Die Bibliothek deckt ein breites Spektrum an Verbindungsmanagement und -optimierung ab, einschließlich Session-Resumption, Pre-Shared-Keys und nicht-blockierendem Netzwerk-I/O mittels benutzerdefinierter Callbacks. Sie bietet zudem umfangreiche Zertifikatsverwaltungstools für die Handhabung von Trust-Stores, die Überprüfung von Widerrufen und die Validierung von Transparenz.
