In basic terms, an electronic signature is just that: a signature in electronic form. It enables signatories to approve or agree with the terms of a document, just like with wet signatures. An electronic signature is essentially a process that uses computers to authenticate the signatory and certify the integrity of the document.

Digital signatures are a type of electronic signature that use complex algorithms, certificate authorities (CAs) and trust service providers (TSPs) to authenticate the signator along with the integrity of the document.
