Signing a multi-page PDF then splitting invalidates signatures due to hash changes. Discover the PKI-approved method: split first, hash and eSign each page individually for valid, tamper-proof documents every time
Multiple eSign in Multi Page PDF – Raj-eSign 2.1 enables secure, legal digital signatures across pages using Aadhaar OTP in government workflows.
Aadhaar eSign eKYC India facilitates digital identity verification and document signing using Aadhaar authentication, promoting paperless, efficient processes. It integrates eKYC and eSign services, ensuring legal validity under Indian law. With key stakeholders involved and significant benefits, it plays a vital role in India’s digital economy, despite some adoption challenges.
A PDF can contain multiple digital signatures, applied sequentially while preserving the validity of previous signatures as long as no unauthorized modifications occur. This process uses incremental signing, ensuring document integrity and creating a verifiable audit trail. Multiple digital signatures are legally recognized in India under the Information Technology Act, 2000.

A documents can be signed using handwritten signatures, scanned signatures, or digital signatures. However, many people are unsure which type of signature is Secure as well as Legally Valid. This confusion is common among professionals who deal with: In this article, I’ll discuss the legal validity, security, and differences between handwritten signatures, scanned signatures, and … Read more
Digital signatures represent the cornerstone of Public Key Infrastructure (PKI), providing cryptographic assurance of document authenticity, integrity, and non-repudiation. These mathematical constructs, based on asymmetric cryptography using private and public key pairs, enable secure electronic transactions across industries, governments, and trust ecosystems. In contrast, eSign is an electronic signature service model that enables users to … Read more
