Digital Signature vs Electronic Signature: Examples, Differences, Pros and Cons

What are Digital Signatures?

Digital signatures are digital security approaches used to provide authenticity and integrity of digital documents or messages.

They consist of the public key infrastructure (PKI) and cryptographic hashing functions, which are used to create unique signatures that are irreversibly linked to the identity of the person who signs them.

With digital signatures, the one who signs uses the private key to hash or digest the document. Therefore, a special digital signature is produced. After that, the digital signature is passed to be added either to the document or message.

If a recipient needs to verify the authentication and legitimacy of a document, he will use the signer’s public key to decrypt the digital signature and a newly computed hash of the received document.

The fact that the decrypted signature equals the signed hash will give assurance that the document has not been tampered with since it was signed and that it was signed by the holder of the corresponding private key.

What are Electronic Signatures?

Electronic signatures (shortened to e-signatures), also known as digital symbols, sounds, or processes that show a person’s agreement or approval on electronically stored documents or transactions, are often used to replace the traditional paper signature.

Unlike digital signatures, which utilize cryptographic computations and each signature the currently known individual participants’ specifics, electronic signatures can more often take any form, and no encryption and other specific security measures could be put into practice.

Electronic signatures give people both the comfort of and effort saving to signing documents and consuming transactions over the internet.

They enable the creation of electronic document management systems, reducing the necessity for physical paperwork and thus shortening processing times plus remote collaboration.

Besides, electronic signatures are commonly taken as legally binding by the majority of legal systems and are seen as an indispensable tool in various industries in both the private sector (e.g., finance, real estate, and healthcare) as well as the public sector.
