- Future-Ready Security: Hybrid Post-Quantum Cryptography support for long-term trust.
PKI Registration Authority Server
The PKI Registration Authority (RA) Server provides a secure and centralized interface for managing digital certificate enrollment and approval within an QuanTrust PKI environment. It enables controlled validation of users, devices, and applications before certificates are issued by the Certification Authority.
Designed for operational efficiency and security, the RA Server streamlines certificate requests, approvals, renewals, and revocations through a web-based interface, while enforcing organizational policies and delegated administration.
Key Capabilities
- Centralized Certificate Enrollment & Approval
Review, approve, renew, or revoke certificate requests through a secure web interface. - Policy-Driven Enrollment Workflows
Supports PKCS#10–based certificate requests for users and servers with configurable approval workflows. - Delegated Administration
Enables separation of certificate management across departments, tenants, or organizations. - Automated Lifecycle Notifications
Alerts administrators for certificate expiration, renewal, and other critical events. - Seamless CA Integration
Works directly with the PKI CA Server for controlled certificate issuance and lifecycle management. - Secure Identity Validation
Ensures only authorized and verified entities are enrolled into the trust infrastructure.
The RA Server acts as the trust enforcement layer between certificate applicants and the Certification Authority, enabling scalable and secure PKI operations for enterprises, governments, and service providers.
OCSP Validation Authority (OCSP Server)
The PKI OCSP Server is a high-performance and reliable certificate validation service that provides real-time certificate status checking in compliance with RFC 6960 and RFC 5019. It acts as a centralized validation authority for one or multiple Certification Authorities (CAs), ensuring trust and continuity in secure communications.
Designed for enterprise and service-provider environments, the OCSP Server delivers fast responses, flexible validation policies, and detailed transaction visibility, making it ideal for high-availability and large-scale PKI deployments.
Key Capabilities
- Standards-Compliant Validation
Fully compliant with RFC 6960 and RFC 5019 for real-time certificate status verification. - Multi-CA Support
Acts as a shared validation hub for multiple Certification Authorities. - High Performance & Scalability
Optimized for high-volume validation requests with low latency response. - Flexible Deployment Models
Supports distributed OCSP responders, repeaters, and front-end OCSP deployments. - Advanced Validation Policies
Supports basic and complex validation rules per CA. - Secure Transaction Logging
All OCSP requests and responses are securely logged for auditing and troubleshooting. - Performance Tuning & Optimization
Configurable logging, in-memory CRL handling, and service separation for optimal throughput. - Role-Based Management & Reporting
Granular access control with detailed transaction and usage reporting.
The OCSP Server serves as the real-time trust validation layer for PKI-enabled systems such as web services, email platforms, VPNs, and enterprise applications, ensuring that only valid and trusted certificates are accepted.
Time Stamping Service (TSA / TSS Server)
The PKI Time Stamping Service (TSA / TSS Server) provides trusted, tamper-proof time verification for digital signatures, electronic documents, and online transactions. It delivers independent proof that a transaction or signature existed at a specific point in time and that the data has not been altered since.
Designed for enterprise and trust service environments, the solution offers high throughput, high availability, and full compliance with international time-stamping standards, making it suitable for both internal enterprise use and commercial TSA services.
Key Capabilities

Optional TSA gateway enables centralized request handling for internal systems using secure SSL-based authentication. - Enterprise & Commercial Ready
Suitable for large enterprises, governments, and third-party trust service providers.
The TSA Server acts as the time trust anchor within a PKI ecosystem, enabling legally reliable digital signatures, long-term document validation, notarization, and compliance-driven workflows.
Designed for enterprise and service-provider environments, the OCSP Server delivers fast responses, flexible validation policies, and detailed transaction visibility, making it ideal for high-availability and large-scale PKI deployments.
Digital Signing Server
The PKI Signing Server enables secure, legally binding digital signatures for documents, transactions, and enterprise workflows. It replaces manual, paper-based signing processes with a trusted, efficient, and auditable digital alternative, ensuring authenticity, integrity, and non-repudiation.
