Types of Certificates Supported by emSign
emSign issues a broad range of publicly trusted digital certificates. These certificates enable secure communication, authentication, integrity, and non-repudiation across internet-facing and trust-critical use cases. emSign certificates are trusted by major browsers, operating systems, and platforms worldwide and are operated under WebTrust-audited environments and CA/Browser Forum requirements.
Below are the primary types of certificates supported by emSign as a publicly trusted CA.
TLS / SSL Certificates
TLS (formerly SSL) certificates are used to secure communication between clients and servers by enabling encrypted connections and authenticated endpoints.
emSign supports:
Domain Validation (DV) TLS Certificates Provide basic encryption and domain ownership validation, commonly used for websites, APIs, and services.
Organization Validation (OV) TLS Certificates Include organizational identity verification, offering stronger assurance for business and enterprise applications.
Extended Validation (EV) TLS Certificates Provide the highest level of identity assurance, involving rigorous organizational validation and enhanced trust indicators where supported.
These certificates are commonly used for websites, SaaS platforms, public APIs, and internet-facing services.
Secure Email (S/MIME) Certificates
S/MIME certificates are used to secure email communications by enabling:
Email encryption to protect message confidentiality
Digital signing to verify sender identity and message integrity
emSign issues publicly trusted S/MIME certificates suitable for individual users and enterprises, enabling secure and authenticated email communication across email clients and platforms.
Code Signing Certificates
Code signing certificates allow software publishers to digitally sign applications, executables, scripts, and updates. This enables end users and operating systems to verify the integrity and authenticity of software before installation or execution.
emSign supports:
Standard code signing certificates
Use cases aligned with operating system and platform trust requirements
These certificates are essential for software distribution, application updates, and maintaining user trust.
Client Authentication Certificates
Client authentication certificates are used to authenticate users or devices to applications, networks, or services. They provide strong, certificate-based authentication without reliance on passwords.
Common use cases include:
Secure access to enterprise applications
VPN and network authentication
Mutual TLS (mTLS) for client-to-service authentication
Document Signing and Digital Signature Certificates
emSign supports publicly trusted digital signature certificates used to sign documents and transactions. These certificates enable:
Integrity and authenticity of digital documents
Non-repudiation of signed content
Legal and regulatory acceptance in supported jurisdictions
These certificates are widely used in business workflows, contracts, and regulated digital transactions.
Timestamping Certificates
Timestamping certificates are used to provide trusted proof that a digital signature or piece of data existed at a specific point in time. This is especially important for:
Long-term validity of digital signatures
Code signing and document signing use cases
Regulatory and audit requirements
Timestamping ensures signatures remain valid even after the signing certificate expires.
