At a Glance: The Core Differences
While often used interchangeably, electronic and digital signatures have distinct characteristics. This table breaks down the essentials to help you understand what sets them apart.
| Feature | Electronic Signature (E-Signature) | Digital Signature |
|---|---|---|
| Concept | A broad legal term for any electronic process that indicates acceptance of an agreement. | A specific, secure technology used to implement electronic signatures. |
| Primary Purpose | To verify a document with the signer's intent. | To secure a document and verify its authenticity and integrity. |
| Method | Can be a typed name, a scanned image of a signature, a click on an "I Agree" button, etc. | Uses cryptographic encryption, specifically Public Key Infrastructure (PKI), to create a unique digital "fingerprint". |
| Security | Security levels vary. eSignly uses advanced methods to secure electronic signatures. | High level of security. Tampering with the document after signing invalidates the signature. |
| Verification | Verified through audit trails, email addresses, IP addresses, and other metadata. | Verified through certificate authorities (CAs) that issue digital certificates. |
| Legal Standing | Legally binding and widely accepted for most business transactions (ESIGN, UETA, eIDAS). | Provides the underlying technology that makes many electronic signatures highly secure and legally defensible. |
| Example Use Case | Sales contracts, HR onboarding forms, vendor agreements, NDAs. | High-security government filings, legally mandated documents, transactions requiring the highest level of identity assurance. |
What is an Electronic Signature?
Think of an electronic signature as the digital equivalent of a handwritten signature. It's a legal concept defined by laws like the U.S. ESIGN Act as an "electronic sound, symbol, or process, attached to or logically associated with a contract or other record and executed or adopted by a person with the intent to sign the record."
-
Intent is Key: The primary function is to capture the signer's intent to be bound by the terms of the document.
-
Broad in Form: It can take many forms, from typing your name into a box to drawing your signature on a screen with your finger.
-
Legally Accepted: It is legally recognized and enforceable for the vast majority of business and personal transactions worldwide.
What is a Digital Signature?
A digital signature is not a signature itself, but a highly secure technology used to protect and authenticate documents. It uses a form of advanced encryption called Public Key Infrastructure (PKI) to create a unique, tamper-evident "fingerprint" on a document.
-
Technology-Based: It's a specific cryptographic method, not a legal definition.
-
Ensures Integrity: If the document is altered in any way after the digital signature is applied, the signature is automatically invalidated, providing clear evidence of tampering.
-
Identity Authentication: It often involves a digital certificate from a trusted third-party Certificate Authority (CA) to verify the signer's identity to a high degree of certainty.
