Introduction to signatures
Nutrient Web SDK streamlines paperless signing workflows with its Electronic Signatures and Digital Signatures components. These two components are available separately and function independently. An electronic signature allows users to sign documents or data electronically, while a digital signature leverages advanced cryptographic techniques to add an extra layer of security to electronically signed documents, ensuring document integrity and authenticity.
