The Difference Between Electronic Signatures and Digital Signatures

Posted 20th April 2022

If you’ve signed a document digitally, there’s a good chance you’ve already used an electronic or digital signature. With traditional ‘wet’ signatures quickly becoming outdated in the modern workplace, more and more businesses will now be considering a more modern, digital alternative.

Whilst the terms electronic and digital signature are often used interchangeably, they are in fact two different ways of signing a document. In this blog, we’ll be discussing the differences between electronic and digital signatures, as well as the key features and benefits.


What Is a Digital Signature?

In the most basic sense, a digital signature refers to the specific technical way in which electronic signatures are implemented. Digital signatures rely on encryption technology, which offers greater security and authenticity.

Digital signatures offer a tamper-proof way of signing digital documents. They also ensure your signer is fully verifiable by linking them to the transaction. To digitally sign a document, you will need a trusted certificate authority or trust service provider. These third-party providers are the ones that validate your digital signature.


How Does a Digital Signature Work?

Whilst you don’t need to know how a digital signature works to use one, it does demonstrate how secure these kinds of transactions are.  Most digital signature providers will comply with a Public Key Infrastructure (PKI) to securely transfer data from one party to another. This uses two ‘keys’ (long numbers generated by an algorithm) to encrypt and decrypt the documents.

When you sign a digital document, an algorithm then creates what’s called a hash- data that is unique to a signed document. This is then encrypted by the signer’s own private key. This encrypted data is what forms a digital signature.

The signed document can then be decrypted on the recipient’s end using a public key (or digital certificate). This generates a second hash, which is then compared with the original. If they both match, then the document is valid.  If the contents of the document are changed or tampered with, however, the two hashes will be different and the document will be invalid.

For us signers, we just need to know this: digital signatures use encryption, keys, and hashes to keep transaction secure and ensure that signatures are valid and authentic.


What Is a Digital Certificate?

A digital certificate also referred to as a public key certificate is an electronic file that contains the public key of the sender and information that identifies the signer. Digital certificates are issued by a certificate authority and are sent alongside the signed document, with the public key then used to decrypt the document.


What Are the Benefits of Digital Signatures?

Digital signatures can bring a number of benefits to your business, including increased productivity and efficiency, reduced turnaround time and streamlined processes. Yet, electronic signatures can also help businesses benefit from digital ways of working. Thanks to the mathematical processes and cryptography technology, digital signatures demonstrate:

  • Authenticity- Thanks to PKI and the digital certificate verifying the identity of the signer, businesses can be sure that both the document and signature they receive are actually from their intended recipient.
  • Integrity- Digital signatures ensure that documents cannot be tampered with once they have been signed, providing peace of mind that transactions are protected from subsequent changes that could be used for malicious or fraudulent purposes.
  • Non-Repudiation- Digital signatures use several steps to verify the signer and record the transaction, ensuring no party can deny signing or sending the document and protecting the transaction from any false claims in the future.

As digital signatures go through greater lengths to record transactions and verify identity, they’re considered to be more secure than regular electronic signatures- which for many businesses and sectors, makes them the preferred choice.


What Is an Electronic Signature?

In comparison to digital signatures, basic electronic signatures are a lot simpler; they’re essentially a digital version of an ink signature. An electronic signature can be anything from a typed/drawn out name, a tick box plus declaration, symbol, or PIN. The eIDAS defines simple electronic signatures as “data in electronic form which is attached to or logically associated with other data in electronic form and which is used by the signatory to sign”.


Digital or E-Signature: Which Is Better?

Digital signatures definitely win out in terms of security, integrity, and authenticity. This makes them best suited for use in business transactions, particularly where sensitive information or high-value transactions are concerned.

With a digital signature on the case, you’ll have peace of mind that your signer is who they say they are and that your document cannot be tampered with. You can also be sure that the transaction details will be recorded by your signature provider.

Whilst digital signatures are significantly more secure than basic e-signatures, that doesn’t mean that they don’t have a place. For more casual documents or agreements, sometimes a tick box plus a declaration or drawn signature is enough to signal agreement, such as when you collect a parcel or agree to the T&Cs on a website.
