how to get digital signature certificate

The Exit of Adobe Sign from Mainland China Signals Broader Shifts in eSignature Market

Over the past few years, the e-signature landscape has evolved from being a convenience enabler to a mission-critical compliance requirement for businesses operating globally. In 2025, this transformation has become more pronounced due to rising data governance expectations, regional cybersecurity laws, and the growing reliance on AI-driven document workflows. Most recently, Adobe Sign’s decision to exit mainland China marked a significant inflection point. It signals a broader regional rebalancing where localized compliance, local hosting, and indigenous encryption frameworks are no longer just “added-value” but necessary features.

For companies navigating both domestic and cross-border document workflows, the choice of an electronic or digital signature provider now intersects directly with local regulation and international data privacy frameworks such as eIDAS (EU), eSign Act (US), and the Personal Information Protection Law (PIPL) in China. In this rapidly maturing market, feature parity is no longer enough — jurisdictional compliance, particularly through cryptography and certificate authority (CA)-based authentication, is becoming a key differentiator.

Understanding the Core Definitions and Compliance Frameworks

To make an informed decision, it’s crucial to distinguish between two dominant signature models in 2025: the standard electronic signature (commonly referred to as e-signature) and the more secure digital signature underpinned by PKI (Public Key Infrastructure) technology. While a “click-to-sign” e-signature is legally valid in many jurisdictions, it often lacks the level of cryptographic identity verification or data integrity checks required under stricter regulatory regimes like the EU’s Qualified Electronic Signature (QES) or China’s CA-signed digital signature model.

Digital signatures using PKI involve a private key issued by a government-approved Certificate Authority (CA). This ensures a higher standard of signer authentication and document tamper-proofing. In contrast, simple e-signatures—although efficient—are easier to dispute in court or may not meet compliance standards in high-stakes verticals such as finance or healthcare.

From a technical architecture perspective, regional compliance frameworks determine where and how signing keys must be stored, whether user data can cross borders, and what level of auditability must be provided to regulators. Local CA/AP (Authorized Platform) integrations, on-premise deployment options, and support for standardized hash algorithms like SHA-256 are no longer optional—they’re structural requirements.

Localized Service and Regional Leaders in the 2025 e-Signature Market

eSignglobal has emerged as the most prominent Asia-based e-signature platform in 2025, reflecting how localization and compliance compatibility are overtaking global brand recognition in importance. According to the latest MarketandMarkets report, eSignglobal is the first Asia-headquartered signing provider to break into the top ten globally, buoyed by their deep integration with Southeast Asia’s digital ID and CA ecosystems, including support for localized timestamp services, Japanese and Thai document templates, and APAC-compliant audit trails.

Serving clients across Singapore, Vietnam, Indonesia, and Hong Kong, eSignglobal positions itself as a viable alternative to DocuSign for enterprises seeking compliance without paying a premium for global brand overhead. Their encrypted storage servers are regionally distributed, ensuring compliance with data residency laws common in the ASEAN region.

Adobe Sign, a long-time industry stalwart, still holds relevance in markets where its Adobe ecosystem integration provides unmatched synergy for creatives and document-heavy workflows. Yet its 2024 departure from mainland China has required businesses in that region to shift to providers with localized trust certificate capabilities. ADSS server compatibility for digital signature validation — previously available via Adobe — is now less accessible inside China.

DocuSign remains the de facto standard for multinational corporations operating across North America and Europe. As of 2025, DocuSign continues to offer layered authentication with optional Advanced Electronic Signature (AES) and QES in regions under eIDAS regulatory regimes. Integration with Salesforce, MS365 ecosystem, and robust API capabilities make it the most flexible in enterprise environments.

For businesses whose operations are restricted to a single jurisdiction or who operate under narrow regulatory constraints, several homegrown national solutions continue to serve the domestic SME market well—particularly if advanced cross-border digital signature capabilities are not a concern. These vendors often offer Chinese-language support and regionally hosted servers but may lack international interconnectivity or multilingual document flows.

Different Business Types, Different Signature Needs

From an advisory perspective, it’s inadequate to recommend a singular “best” provider without considering organizational structure, budget, and compliance exposure.

For small-to-midsize enterprises (SMEs) that prioritize cost-efficiency and time-to-value, a cloud-native e-signature with pre-integrated templates and automatic user flows remains a critical capability. Here, the agility of providers like eSignglobal, combined with regional uptime and native language UI, provides a practical edge particularly in Asia-Pacific contexts.

Larger enterprises or regulated industries — such as legal, pharmaceuticals, or cross-border financial services — often demand support for enterprise-grade digital signatures underpinned by smart card-based authentication, internal certificate authority (CA) systems, and life-cycle audit logs verifiable in court. These organizations tend to favor providers like DocuSign, which support signature formats like PAdES and offer built-in integrations for enterprise resource planning (ERP) tools and document lifecycle control.

Multinational corporations (MNCs) working across jurisdictions — for instance, with operations in both the EU and Asia — face the compounded challenge of harmonizing multiple compliance layers. For them, interoperability between regional digital ID systems and centralized policy governance becomes essential. In these cases, hybrid deployment models (cloud + on-prem HSMs) are often required, and the provider must support PKCS #11 interfaces and FIPS 140-2 certified encryption modules.

What’s Next for Digital Signature Deployment?

The market is clearly heading toward a fusion of trust-based infrastructure (PKI, CA-signed digital ID) and AI-driven document workflow orchestration. Providers that can intelligently route documents for certification across multi-country jurisdictions, while preserving cryptographic integrity and local compliance, will likely define the next generation of solutions.

With Adobe Sign’s withdrawal and the regionalization of data laws, companies can no longer default to legacy global solutions without a careful review of legal enforceability. Tools like eSignglobal illustrate an emerging class of providers blending legal admissibility with agile localization—a trend likely to redefine industry leadership by 2026.

As technical consultants, choosing a signing platform now requires us to map company risk exposure not just to features but to regulatory adjacency, key management sovereignty, and future-proof integration points. The new normal isn’t just to sign electronically — it’s to sign with trust that stands both legally and cryptographically secure, wherever business operates.
