For close to two decades, we have contributed to national and organisation-wide solutions covering eID-based signing, document encryption, validation, and the integration of trust services into existing information systems. Our experience spans from end-user applications and signing workflows to the underlying cryptographic and trust infrastructure that enables them.
For us, digital signatures are inseparable from a broader trust framework. Our services, therefore, include certificate management, PKI architecture, timestamping and validation services, and alignment with European and international regulatory requirements. We work with solutions that withstand both technical audits and legal scrutiny, and that integrate seamlessly with national identity and trust ecosystems. RaulWalter does not merely deliver tools — we help build the trust foundations on which critical digital services can reliably operate over the long term.
The result – robust, interoperable trust services that provide a legally sound foundation for digital processes and critical services — today and in the future.
We design and implement legally valid digital signature solutions based on national eID schemes and recognised trust frameworks. This includes end-user signing applications, server-side signing, workflow integration, and document lifecycle handling. Solutions are designed for usability while preserving evidential strength and legal enforceability.
We design, assess, and implement Public Key Infrastructure (PKI) components that underpin trust services. This includes CA hierarchy design, key management, certificate issuance and revocation, and lifecycle governance. PKI architectures are built to meet both technical security requirements and regulatory expectations.
We integrate digital signature and trust services into existing information systems and service platforms. This includes API-level integration, service orchestration, and alignment with registry and data exchange layers. Trust services are embedded as core infrastructure rather than isolated components.
We implement validation, timestamping, and long-term preservation mechanisms that ensure digital signatures remain verifiable over time. This includes compliance with long-term validation profiles, evidential integrity, and cryptographic agility. The result is trust that persists beyond individual technologies and algorithms.
We align trust service implementations with European and international regulatory frameworks and audit requirements. This includes support for technical audits, legal assessments, conformity checks, and operational procedures. Solutions are designed to withstand both cryptographic scrutiny and legal challenge.
