Digital Signature Definition and Examples

Understanding Digital Signature for e-Signing

A digital signature is more than just an electronic scribble on a screen. It's a cryptographic mechanism that ensures the authenticity and integrity of digital documents. Unlike traditional ink signatures, digital signatures provide robust security features that prevent tampering and verify the signer's identity. Here’s why understanding digital signatures is crucial for modern businesses, especially when choosing an e-signature provider like GoodSign.

What is a Digital Signature?

A digital signature is a mathematical technique used to validate the authenticity and integrity of a message, software, or digital document. It is the digital equivalent of a handwritten signature or a stamped seal, but it offers far more inherent security. Digital signatures are based on Public Key Infrastructure (PKI), a framework that uses two keys – a private key and a public key.

When a signer electronically signs a document, their private key is used to create a unique signature. The recipient can then use the signer's public key to verify the signature’s authenticity. Any alteration made to the document after signing invalidates the signature, making digital signatures highly effective in preventing document tampering.

Benefits of Digital Signatures
