Confused about electronic signatures vs digital signatures? You're not alone. This comprehensive guide explains the differences, security features, legal validity, and which type you actually need for your business.
Here's what you need to know at a glance
| Feature | Electronic Signature (E-Signature) | Digital Signature |
|---|---|---|
| Technology Used | Basic verification (email, SMS, IP) | PKI cryptography with certificates |
| Security Level | Good for most business needs | Highest security with encryption |
| Tamper Detection | Audit trail only | Cryptographic proof |
| Ease of Use | Very Easy | Complex Setup |
| Cost | $12-50/month | $100+/month + certificates |
| Legal Validity | Legally binding | Legally binding |
| Signer Experience | Sign in 60 seconds | Requires certificates/setup |
| Best For | Business contracts, proposals, HR | Government, finance, healthcare |
For 95% of businesses, secure e-signatures like BoopSign provide all the protection you need at a fraction of the cost and complexity. Digital signatures are overkill unless you're in heavily regulated industries or dealing with extremely sensitive documents.
An electronic signature is any digital method of indicating your intent to sign a document or agreement. It's the broad umbrella term that includes everything from typing your name at the end of an email to using sophisticated signing platforms like BoopSign.
E-signatures focus on ease of use and accessibility while still providing legal validity. They've become the standard for business contracts, proposals, HR documents, and everyday agreements because they're fast, convenient, and legally compliant.

Signature Encryption
The hash is encrypted with your private key to create the signature
Verification
Recipients use the public key to verify authenticity and detect tampering
A digital signature is a specific type of electronic signature that uses PKI (Public Key Infrastructure) cryptography to provide the highest level of security, authentication, and tamper detection.
Think of it as an electronic fingerprint that's mathematically bound to both the document and the signer. Any change to the document—even a single character—invalidates the signature, making forgery virtually impossible.
Digital signatures are required for highly regulated industries (government, finance, healthcare) and international transactions where maximum security and non-repudiation are essential.
Understanding these distinctions helps you choose the right signature type for your needs
E-Signatures:
Use basic verification methods like email, SMS codes, IP addresses, and timestamps. Modern platforms add audit trails and encryption for extra security.
Digital Signatures:
Use PKI cryptography with digital certificates from trusted authorities. Provide mathematical proof of identity and document integrity.
E-Signatures:
Rely on audit trails to track changes. You can see if something changed, but there's no cryptographic lock preventing alterations.
Digital Signatures:
Any change to the document invalidates the signature immediately. The cryptographic hash detects even single character modifications.
E-Signatures:
Extremely simple. Click a link, review the document, sign in seconds. No setup, no certificates, no technical knowledge required.
Digital Signatures:
Complex setup required. Must obtain digital certificates, install software, manage private keys, and understand PKI infrastructure.
E-Signatures:
Affordable at $12-50/month for unlimited signatures. BoopSign is just $12/month with no per-signature fees or hidden costs.
Digital Signatures:
Expensive at $100+/month plus certificate costs ($50-200 annually per user). Total costs can reach $1,000+/year per user.
E-Signatures:
Verify identity through email confirmation, phone verification, or knowledge-based authentication. Good enough for most business needs.
Digital Signatures:
Identity verified by trusted Certificate Authorities using government IDs and background checks. Highest level of authentication.
E-Signatures:
Legally binding under ESIGN Act (US) and eIDAS (EU) for most business documents. Accepted in 60+ countries worldwide.
Digital Signatures:
Also legally binding with additional compliance for regulated industries. Required for some government and international transactions.
