Electronic signatures, or e-signatures, refer broadly to any electronic process that indicates acceptance of an agreement or a record. The term digital signature is frequently used to refer to one specific type of electronic signature. 1  Typical e-signature solutions use common electronic authentication methods to verify signer identity, such as email, corporate IDs, or a phone PIN. 2  Digital signatures use a specific type of electronic signature.
When you apply a Digital Signature to a document, a cryptographic operation binds your digital certificate and the data being signed into one unique fingerprint. The uniqueness of the two components of the signature are what makes digital signatures a viable replacement to wet ink signatures. For further detailed explanation, see how Digital Signatures work. In summary, the cryptographic operation allows Digital Signatures to verify and assure the following: 1  The document is authentic and comes from a verified source. 2  The document has not been tampered with since being digitally signed as the signature would be displayed as invalid if changes were made.
