Electronic Signature
An electronic signature is any electronic expression of consent to a document's content — from a scanned handwritten signature to a cryptographically secured qualified signature.
Full Definition
The eIDAS regulation defines three levels: simple, advanced and qualified. For most commercial documents (contracts, NDAs, purchase orders) an advanced electronic signature is sufficient and legally binding across the EU. A qualified signature requires a certificate issued by an accredited CA and a special device (e.g. a smart card).
