What is an Electronic Signature?
An electronic signature (or e-signature) is any digital mark used to indicate agreement or approval of a document — replacing the traditional handwritten signature in digital workflows. E-signatures are legally recognized in most countries: USA (ESIGN Act, 2000), EU (eIDAS Regulation, 2016), UK (Electronic Communications Act), Canada (PIPEDA), and many others.
Unlike a cryptographic digital signature (which uses PKI certificates for identity verification), an electronic signature is simply a visual mark: a drawn signature, a typed name in a handwritten font, or an uploaded image of your handwriting. For most personal and business documents — contracts, NDAs, rental agreements, invoices, consent forms, offer letters — an e-signature is fully sufficient and legally valid.
