Demystifying Terminology: Electronic Signature vs Digital Signature
While often used interchangeably in everyday business, 'electronic signatures' and 'cryptographic digital signatures' refer to fundamentally different technical constructs:
An Electronic Signature (e-signature) encompasses any electronic symbol, mark, typed cursive name, or scanned handwritten image attached to a document to demonstrate intent to sign. Recognized under the US ESIGN Act and EU eIDAS regulations (Simple Electronic Signature tier), it is widely accepted for everyday business contracts, NDAs, invoices, and employment agreements.
A Digital Signature is a specific cryptographic implementation relying on Public Key Infrastructure (PKI). It binds a mathematical hash of the document to an identity certificate issued by a trusted Certificate Authority (CA), verifying tamper-evident integrity.
When Is an Electronic Signature Legally Binding?
In the majority of commercial jurisdictions, an electronic signature is legally enforceable if five foundational criteria are met:
1. Intent to Sign: The signer takes an explicit action confirming agreement.
2. Consent to Electronic Business: Parties agree to conduct transactions digitally.
3. Clear Association: The signature is visibly linked to the executed agreement.
4. Attribution: A verifiable audit trail or email correspondence connects the signer to the transaction.
5. Document Integrity: The signed document is preserved without post-execution alterations.
- After placing a signature image on a PDF form, use 'Flatten PDF' to bake the signature into the document content stream, preventing accidental field displacement.
- Export your signature with a transparent background PNG so it overlays cleanly onto contract lines without obscuring surrounding text.
