What is Aadhaar E-Sign?
Aadhaar e-Sign is a legally valid electronic signature service authorized under the Information Technology Act 2000 (Section 3A) and IT Rules 2021. It enables paperless signing of documents using Aadhaar-based authentication provided by UIDAI (Unique Identification Authority of India). This digital signature method is recognized by Indian courts and government authorities as equivalent to physical signatures.
Under the IT Act 2000, e-signatures created through Aadhaar authentication are valid for contracts, agreements, legal documents, and applications. The system uses advanced cryptographic techniques (2048-bit encryption) to ensure document integrity and non-repudiation. Every e-signature is backed by a Digital Signature Certificate (DSC) from a licensed Certifying Authority, making it admissible as evidence under Section 65B of Indian Evidence Act 1872.
