About Root Certificates in SSL / TLS

Root SSL Certificates form the foundation of secure online communications, and Trustico® is a leading provider of trusted SSL Certificate solutions.

As experts in SSL Certificate technology, we help organizations understand and implement the right SSL Certificate solutions for their security needs. Our portfolio includes both Trustico® and Sectigo® branded SSL Certificates to provide maximum flexibility and trust.

Understanding Root SSL Certificates

A Root SSL Certificate acts as the trusted anchor in the SSL Certificate chain of trust. When you purchase a Trustico® SSL Certificate, it inherits its trust from a Root SSL Certificate maintained by our trusted Certificate Authority (CA) partner Sectigo®.

This hierarchical structure ensures the highest levels of security and authentication for your online presence.

Root SSL Certificates are meticulously protected and managed under strict security protocols.

Trustico® SSL Certificates benefit from this robust infrastructure while providing streamlined validation and issuance processes for our customers.

The creation and management of Root SSL Certificates involve extraordinary security measures far beyond typical cybersecurity practices. Root SSL Certificate private keys are generated and stored in specialized hardware security modules (HSMs) in highly secure, access-controlled facilities with multiple layers of physical and electronic protection.

Certificate Authorities (CA) like Sectigo® conduct elaborate key generation ceremonies when creating new Root SSL Certificates. These ceremonies follow meticulously documented procedures with multiple trusted individuals present, often including independent auditors and witnesses.

The extreme care taken in these processes underscores the critical importance of Root SSL Certificates in the global security infrastructure.

Technical Structure of Root SSL Certificates

Root SSL Certificates possess a unique technical characteristic that distinguishes them from other SSL Certificates : they are self-signed.

This means the digital signature on the Root SSL Certificate is created using its own private key rather than being signed by another authority. This self-signed nature is why establishing trust in Root SSL Certificates requires special distribution and verification methods.

The cryptographic strength of Root SSL Certificates is paramount to the security of the entire SSL Certificate ecosystem. Modern Root SSL Certificates typically use RSA keys of 4096 bits or equivalent ECC keys, providing substantial cryptographic security margins.

This robust foundation ensures that Trustico® SSL Certificates derived from these roots maintain the highest security standards.

Root SSL Certificates have significantly longer validity periods than standard SSL Certificates, often extending to 20-25 years. This extended lifespan is necessary for stability in the trust ecosystem but requires careful planning for eventual replacement and cross-signing to maintain continuity of trust. Trustico® monitors these lifecycle events to ensure our customers' SSL Certificates remain trusted throughout their validity period.

Browser and operating system trust stores contain a carefully curated collection of Root SSL Certificates from approved Certificate Authorities (CA). These trust stores determine which SSL Certificates will be automatically trusted by users' devices.

Sectigo® Root SSL Certificates, which anchor Trustico® SSL Certificates, are included in all major trust stores, ensuring universal compatibility and recognition.

The SSL Certificate Chain of Trust

Every Trustico® SSL Certificate is part of a carefully structured chain of trust. The Root SSL Certificate signs an Intermediate SSL Certificate, which in turn signs your end-entity SSL Certificate. This creates a verifiable chain that browsers and systems can validate to ensure secure connections.

Our partnership with Sectigo® enables us to offer SSL Certificates that are recognized by all major browsers and operating systems. The established root program ensures universal compatibility and trust for your secure communications. Trustico® provides both Domain Validated (DV) and Organization Validated (OV) SSL Certificates to meet varying security requirements.

Intermediate SSL Certificates serve a critical role in the chain of trust by creating a protective buffer between high-value Root SSL Certificates and daily operational SSL Certificate issuance.

This architecture allows Root SSL Certificate private keys to remain offline in secure storage while Intermediate SSL Certificate keys handle routine signing operations. Trustico® SSL Certificates benefit from this security-focused design.

SSL Certificate path validation is the process by which browsers and operating systems verify the chain of trust from your Trustico® SSL Certificate back to a trusted Root SSL Certificate. This validation includes checking digital signatures, validity periods, revocation status, and critical extensions for each SSL Certificate in the chain. Proper chain configuration is essential for your SSL Certificate to be trusted without errors or warnings.

Root SSL Certificate Programs and Governance

Root SSL Certificate programs operated by major browser and operating system vendors establish strict requirements for Certificate Authorities (CA). These programs conduct rigorous audits and compliance checks before accepting Root SSL Certificates into their trust stores.

Sectigo® Root SSL Certificates, which anchor Trustico® SSL Certificates, maintain compliance with these demanding requirements.

The CA/Browser Forum, an industry consortium of Certificate Authorities (CA) and browser vendors, establishes baseline requirements and guidelines for SSL Certificate issuance and management.

These standards govern everything from validation practices to SSL Certificate lifespans and technical parameters. Trustico® SSL Certificates adhere to these industry standards, ensuring consistent security and compatibility.

Root SSL Certificate governance includes incident response procedures for addressing security compromises or compliance failures. If a Certificate Authority (CA) experiences a serious security incident, browser vendors may distrust their Root SSL Certificates, potentially affecting millions of websites.

Sectigo® maintains robust security practices and incident response capabilities to protect the integrity of the Root SSL Certificates that anchor Trustico® SSL Certificates.

Certificate Transparency (CT) logging has become a mandatory requirement for publicly trusted SSL Certificates. This system creates an append-only public ledger of all issued SSL Certificates, enhancing accountability and security in the SSL Certificate ecosystem.

All Trustico® SSL Certificates are properly logged in CT logs, meeting this important security requirement.

Implementation Best Practices

Proper SSL Certificate implementation is crucial for maintaining secure communications.

Regular SSL Certificate monitoring and timely renewals are essential for uninterrupted security. Trustico® offers automated renewal reminders and management tools to prevent SSL Certificate expiration.

Complete chain installation is critical for proper SSL Certificate functionality. Many server configurations require manual installation of intermediate SSL Certificates to establish the full chain of trust back to the Root SSL Certificate. Trustico® provides complete SSL Certificate and chain bundles to ensure your SSL Certificate chain is properly configured.

Private key security represents one of the most important aspects of SSL Certificate implementation.

While Trustico® ensures the security of Root and Intermediate SSL Certificates, customers must properly secure the private keys associated with their end-entity SSL Certificates.

Certificate revocation checking should be properly configured on servers using Trustico® SSL Certificates. Online Certificate Status Protocol (OCSP) and Certificate Revocation Lists (CRLs) provide mechanisms for checking if an SSL Certificate has been revoked. Enabling OCSP stapling on your server improves performance and privacy while maintaining security.

Advanced SSL Certificate Features

Modern Trustico® SSL Certificates support advanced features that enhance security and performance. HTTP/2 and upcoming HTTP/3 protocols require SSL Certificate encryption, and our SSL Certificates enable these performance-enhancing protocols. This combination of security and speed provides an optimal experience for your website visitors.

Certificate Transparency (CT) compliance is built into all Trustico® SSL Certificates. This important security feature creates a public, verifiable record of all issued SSL Certificates, helping detect unauthorized SSL Certificate issuance and improving overall trust in the web PKI ecosystem. CT logs provide an additional layer of security verification beyond the traditional chain of trust.

Extended Key Usage constraints in Trustico® SSL Certificates precisely define what the SSL Certificate can be used for. Website SSL Certificates include the "serverAuth" (TLS Web Server Authentication) purpose, ensuring the SSL Certificate is used appropriately. These constraints help maintain the security boundaries between different types of SSL Certificates in the PKI ecosystem.

Subject Alternative Name (SAN) extensions allow a single Trustico® SSL Certificate to secure multiple domain names. This extension is essential for Multi-Domain SSL Certificates and is how modern browsers determine which domains the SSL Certificate legitimately covers. Properly configured SAN fields ensure your SSL Certificate protects all your intended domains.
