A CA (Certificate Authority) is a core component within a Public Key Infrastructure (PKI) that issues, signs, manages, and revokes digital certificates. A PKI vendor, by contrast, provides a full suite of products and services around key‑management, including CAs, Registration Authorities (RAs), Hardware Security Modules (HSMs), directory services, governance dashboards, and integration toolkits. In other words:
- CA: The trust anchor that vouches for identities by digitally signing X.509 certificates.
- PKI Vendor: The vendor or solution provider that delivers all the building blocks—CAs, CLM, HSM integration, policy engines, and lifecycle orchestration—needed to run a complete, enterprise‑grade PKI.
Where eMudhra’s Enterprise CA Fits in Key‑Management
eMudhra’s enterprise CA (the emCA Certificate Engine) is the heart of a holistic key‑management ecosystem, positioning itself as both the issuance authority and the orchestration hub for cryptographic keys across all digital use cases:
- Root of Trust & Hierarchical Issuance
- Acts as the signing authority for intermediate CAs, code‑signing authorities, device‑authentication CAs, and cloud‑native PKI tiers.
- Establishes a trust hierarchy that segments duties (e.g., public SSL/TLS vs. private IoT certificates) while anchoring all certificates to a common root.
- Integration with HSM‑Backed Key Stores
- All private keys—root, intermediate, and end‑entity—are generated and secured within FIPS‑certified HSMs.
- Provides secure key import/export, backup, and split‑key (M of N) capabilities for disaster‑recovery and shared‑control use cases.
- Centralized Lifecycle Management
- Works with eMudhra’s CLM to automatically enroll, renew, rotate, and revoke keys and certificates according to policy.
- Maintains a unified inventory of keys (symmetric and asymmetric), certificates, and associated metadata across on‑prem and cloud environments.
- Policy‑Driven Governance & Compliance
- Enforces corporate key‑management policies—key sizes, algorithms, validity periods—through certificate templates and issuance workflows.
- Generates detailed audit logs and compliance reports to demonstrate adherence to regulations like PCI‑DSS, HIPAA, GDPR, and local digital‑signature laws.
- Extensible API‑First Architecture
- Exposes RESTful endpoints for key lifecycle operations, enabling DevOps pipelines to programmatically generate, use, and retire keys.
- Integrates with directory services (LDAP/AD), cloud platforms (AWS KMS, Azure Key Vault), and orchestration tools (Ansible, Terraform) for seamless key‑management across the enterprise.
